Some empty lines would allow the code room to breathe, for example in the play function. The complete code is also available on my Github account. You tell the function when to do something, not ask it if it's ready to do it/if it has it. A ticket number is considered lucky if the sum of the first half of the digits is equal to the sum of the second half. Given a sequence of integers as an array, determine whether it is possible to obtain a strictly increasing sequence by removing no more than one element from the array. First you create a list of indices, set the mines and then.. setAdjacentMines - why? F-strings: Python 3.6 and later have this capability; f-strings can make reading print statements much easier. // There is no one element in this array that can be removed in order to get a strictly increasing, // You can remove 3 from the array to get the strictly increasing sequence [1, 2]. If nothing happens, download GitHub Desktop and try again. A string consisting of English letters, punctuation marks, whitespace characters and brackets. Given a string, check if it is a palindrome. Input validation is a very important topic in programming, due to all sorts of bugs and attacks like Cross-Site-Scripting (XSS) and SQL Injection. It can be done by 'import os' at the start of the program. Generally I would make those specific to the class; you need this to understand most of the methods in it anyway. What is the correct way to screw wall and ceiling drywalls? This is because the code begins running as soon as Python loads it, when the intent of the documentor was just to analyse the code. Your MineBoard class explicitly inherits from object. CodeSignal Solutions with time and space complexity for the Arcade, Interview Practice, and Company Challenges. [input] array.array.boolean matrix I added a remark that only the pop()s should be fixed and offered a 2D slicing as alternative Codefights, minesweeper, python, code almost working, How Intuit democratizes AI development across teams through reusability. The literal 7 appears a few times in printLayout. In the given example all boundary pixels were cropped, and the value of the pixel in the middle was obtained as (1 + 1 + 1 + 1 + 7 + 1 + 1 + 1 + 1) / 9 = 15 / 9 = rounded down = 1. For the first example below, the output should be true. For classes, be aware of what variables which are internal/private, and place an underscore _ before them. In the next couple of posts we are going to play Minesweeper in . Cannot retrieve contributors at this time.

One of them is the IPv4 address. recursive (d) /* get the value of one lower d*/ - ( (mainarray [rownumber + ~- (d/3)] || 0) The second candidate can win if all the remaining candidates vote for him (3 + 3 = 6 > 5). This version is a little different to the others out there in that it's supposed to start by asking the user how big the grid, then how many mines to insert. The first person goes into team 1, the second goes into team 2, the third goes into team 1 again, the fourth into team 2, and so on. Now, if you care about static type safety or not, that is a subjective opinion, so you may ignore these Errors. Returning values from functions that aren't used - but as a way to exit the function, Not using a proper data structure to represent the tiles and their behaviour, Spelling/Grammar mistakes in the information presented to the user, Game not acting properly when flagging a single mine (3x3, 1 mine) - finishing automatically, Game not acting properly when flagging a single mine (5x5, 1 mine) due to lower-case f. Asking for help, clarification, or responding to other answers. Call two arms equally strong if the heaviest weights they each are able to lift are equal. For any queries, feel free to comment below. Given an array of integers, find the pair of adjacent elements that has the largest product and return that product.ding the year 100, the second - from the year 101 up to and including the year 200, etc. using " instead of '). You can't just call it and check its result value in a test, for example, you actually have to capture the output from the terminal. This repository includes my solutions for the arcade challenges in CodeSignal. Initially, plant is 0 meters tall. Then you can use groups 1, 2 and 3 to retrieve the values. There is absolutely no reason to use Python 2 for new code in 2021. Is there a single-word adjective for "having exceptionally strong moral principles"? A tag already exists with the provided branch name. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. I love how you help to suggest some other names for my variables. I don't exactly get what it is supposed to do at first glance, even after looking at the conventions. It results in more readable code and a more logical flow than checking the bounds every time. A non-negative integer representing the heaviest weight you can lift with your left arm. You signed in with another tab or window. It means that throughout the years your balance would be: Thus, it will take 3 years for your balance to pass the threshold, which is the answer. We keep doing this until we get the said number of mines. Why are Suriname, Belize, and Guinea-Bissau classified as "Small Island Developing States"? A square grid is rather easy to create using Python by: The grid displayed in each iteration resembles the following figure: The 'M' symbol denotes the presence of a mine in that cell. Does Python have a ternary conditional operator? When this count is equal to the total cells, except those containing mines, then the game is regarded as over. An n-interesting polygon is obtained by taking the n - 1-interesting polygon and appending 1-interesting polygons to its rim, side by side. On subsequent games, I failed again because of this input-handling problem. Does a barbarian benefit from the fast movement ability while wearing medium armor? PEP8: PEP8 talks about using snake_case for variable/function naming (whilst class naming is CamelCase) and a few other things. // Strings can be rearranged in the following way: "aa", "ab", "bb".

RSA Algorithm: Theory and Implementation in Python. After some thought, your first guess is that each consecutive 8 bits of the code stand for the character with the corresponding extended ASCII code. However, it really should not exist at all. [input] integer yourLeft Some obvious classes for a Minesweeper game would include for example Game, Board and Tile. A good example is a set of code checking every minute "is it now 7am?" The lifeline of this program is the recursive function - playMinesweeperUtil () This function returns a true if the user steps/clicks on a mine and hence he loses else if he step/click on a safe cell, then we get the count of mines surrounding that cell. Learn more about bidirectional Unicode characters. Thanks Felicity for your post. In my coding interview for a company, I got the question to write a Minesweeper game. If input: Could anyone explain clearly why that's happening? In other words: if we reach the if at all, we know that all the ifs before it were false, because otherwise we would already have returned from the method. Given an array of strings, return another array containing all of its longest strings. About an argument in Famine, Affluence and Morality, Euler: A baby on his lap, a cat on his back thats how he wrote his immortal works (origin?). Construct a square matrix with a size N N containing integers from 1 to N * N in a spiral order, starting from top-left and in clockwise direction. rev2023.3.3.43278. Find the minimal number of moves required to obtain a strictly increasing sequence from the input. Regardless, thank you for your feedback. To learn more, see our tips on writing great answers. Do you see how this might be confusing to someone that is reading your code? You signed in with another tab or window. However, it is also rather dangerous. Given array of integers, find the maximal possible sum of some of its k consecutive elements. And then in play, the two calls to game.print_layout() can simply be replaced by print(game). Alternately, you. All that said, after I concluded the review I understood the class design and would be able to alter it. A string representing time in HH:MM format. I have written this code in Python 3: def arrayChange (inputArray): original = inputArray [:] count = 0 if len (set (inputArray)) == 1: return ( (len (inputArray)-1)**2 + (len . Code submitted as solutions to the exercises in CodeSignal. This way, the main entry point will only be automatically executed if the module is run as a script, but not if it is imported: Since you intend to run this as a script, it should have a shebang line, something like this: Note: In order to make this answer useful for future readers, I have mostly assumed Python 3.10, which is about to be released soon. Beware that comments that are somewhere within the code tend to get lost. This file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below. All of them are fully functional. So it definitely passed that test. Finally, all the new strings are concatenated together in the same order and a new string is returned. For example, as mentioned, if I simply save your code into a file and open that file in an editor, I get 157 Errors, 44 Warnings, and 21 Infos. But more importantly, the reason why it is hard to give it a proper name is that it appears to be doing too much. Why are non-Western countries siding with China in the UN? Example. Each year the amount of money on your account increases by 20%. You are given an array of positive integers - the weights of the people. @KennyOstrom I don't see an issue with it. Why are trials on "Law & Order" in the New York Supreme Court? A tag already exists with the provided branch name. Let's define digit degree of some positive integer as the number of times we need to replace this number with the sum of its digits until we get to a one digit number. Here's just a couple that my editor flagged: Note that, if we ignore the afore-mentioned undefined types, then the naming accounts for a vast majority of the remaining issues my editor reports. Aftermath of few hours of creating a game of Minesweeper. They should convey meaning. Whether the cell to be flagged is already displayed to the player. Additionally, you don't need to generate this list yourself, you can use random.sample: You're using this method in several places inside loops. In general I would prefer a game where the methods make sure you cannot cheat. [input] char symbol It seems that a click is also opening mines around the clicked location. you can't take two first items or two second items. What is the duration of the longest call (in minutes rounded down to the nearest integer) you can have? How can I remove a key from a Python dictionary? click is used as a method name. Given a ticket number n, determine if it's lucky or not. The digits sum up to 0 + 4 + 0 + 0 = 4, which is the answer. The largest integer divisible by 3 and not larger than 10 is 9. Run code live in your browser. Given an integer product, find the smallest positive (i.e. Call two people equally strong if their strongest arms are equally strong (the strongest arm can be both the right and the left), and so are their weakest arms. The algorithm works as follows: each pixel x in the resulting image has a value equal to the average value of the input image pixels' values from the 3 3 square with the center at x. Note that there are only two items and you can't bring more than one item of each type, i.e. There are two versions of the Internet protocol, and thus two versions of addresses. Non-empty string consisting of lowercase English characters.

However, any recommendations for optimisation are welcome! All possible sums of 2 consecutive elements are: [input] array.integer inputArray Does Counterspell prevent from any further spells being cast on a given turn? The variables are the board squares, which each contain either a mine or a constant between 0 and 8. Through hands-on projects, students gain exposure to the theory behind graph search algorithms, classification, optimization, reinforcement learning, and other . true if inputString is a palindrome, false otherwise. Is there a proper earth ground point in this switch box? Return an array of two integers, where the first element is the total weight of team 1, and the second element is the total weight of team 2 after the division is complete. The nature of simulating nature: A Q&A with IBM Quantum researcher Dr. Jamie We've added a "Necessary cookies only" option to the cookie consent popup. A big clue is the fact that you have multiple comments talking about "cells" but you have no abstraction called "cell" in your code. A set of values that can be assigned to the variables. If there is no such integer, return -1 instead. There must be something in that :). Two cells are called neighboring if they share at least one corner.'''. A non-empty array of strings of lowercase letters. For this particular concept of the game, a new data structure is used, namely, vis. "what about, are you this instead?" Sometimes, you use two blank lines between methods, sometimes only one. 2-dimensional array of integers representing a rectangular matrix of the building. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. Write and run code in 50+ languages online with Replit, a powerful IDE, compiler, & interpreter. The nice thing about style checkers, linters, and static analyzers with auto-correction support, and automatic code formatters is that they do (part of) your work for you. He knows a lot about art and his advice is usually good, but not this time: the performance turned out to be awfully dull. Write a function that returns the sum of two numbers. The complete move therefore looks like the letter L. Check out the image below to see all valid moves for a knight piece that is placed on one of the central squares. Check if the given string is a correct variable name. rev2023.3.3.43278. Single mine flagging: In typical minesweeper, even when there is one mine remaining (flagged or unflagged), tiles that are unclicked still require clicking. The first item weighs weight1 and is worth value1, and the second item weighs weight2 and is worth value2. A non-empty array of integers, sorted in ascending order. Note: The randint function can only be used after importing the random library. Personally I don't like it when click hides other functionality, I'd put that in a calling function. You should choose one style and stick with it. Does Python have a string 'contains' substring method? Thanks !! In this video, we will implement a game of minesweeper in Python! It is guaranteed that the first two characters, as well as the last two characters, are digits. minesweeper codesignal The Blog. Ticket numbers usually consist of an even number of digits. Making statements based on opinion; back them up with references or personal experience. And I get the code formatted according to my preferences (e.g. An easy way to get to the adjacent positions is to prepare a list of offsets for the 8 neighbouring cells based on the row and column numbers. In fact, when you instantiate it, you actually assign it to a variable named game! Given a valid email address, find its domain part. Given your and your friend's arms' lifting capabilities find out if you two are equally strong. I like this, and the fact that you use a separate call to print the board. A limit involving the quotient of two sums. A string consisting of digits, full stops and lowercase Latin letters. Imports: Unused imports hint that perhaps you're not fully aware of all the actions of your scripts? This point might be a little complicated, but patterns like Observer can simplify this process. minesweeper1 = mainarray => // an arrow function, that gets the two d array passed !mainarray.some ( (row,rownumber) => row.some ( (field,columnumber) =>//checking the 2d array if some of the fields field //and the magic recursive function is true d-- ? Where does this (supposedly) Gibson quote come from? It looks like you are missing an abstraction, probably something like a Cell (which could be a namedtuple or a dataclass). This file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below. The neighbours function is a recursive one, solving our problem. Do read comments as they explain a lot and also every block of code. I was trying to make that cautionary point. Game Loop is a very crucial part of the game. one with mines (and mine counts, for convenience) and one layer that shows if the position has been revealed or flagged. It only takes a minute to sign up. For consistency, I'd use a list of tuples for the mine locations. Find the longest word from the given string. Return true if it is possible to remove one element from the array in order to get a strictly increasing sequence, otherwise return false. Cheers! After all the cells with zero value and their neighbours are displayed, we can move on to the last scenario. Looking at the line after having a coffee :) it's a good idea to separate the messge to the user (use print(msg)), and what input you're receiving (, How Intuit democratizes AI development across teams through reusability. Making statements based on opinion; back them up with references or personal experience. Also, I have them set to pretty aggressive settings, which can sometimes be annoying and overwhelming if you work with code that you haven't freshly written yourself. Given a string, return its encoding defined as follows: Given a position of a knight on the standard chessboard, find the number of different moves the knight can perform. Given a string, output its longest prefix which contains only digits. The trickiest part of creating the game is managing this scenario. Such important information, and such an encoding should be encapsulated in an object. Non-empty array of positive integers. Theoretically Correct vs Practical Notation. [input] array.integer a [input] array.array.integer image Why do small African island nations perform better than African continental nations, considering democracy and human development? Funny that we came to the dual layer / dual classes approach seperately. I was given 15 minutes to solve this in a coding challenge, and still can't figure out for the life of me how someone would have approached this. A string of lowercase letters. Yes, you are correct. Is there a single-word adjective for "having exceptionally strong moral principles"? Remove the import. Given an array of equal-length strings, check if it is possible to rearrange the strings in such a way that after the rearrangement the strings at consecutive positions would differ by exactly one character. Read on for a walkthrough of how the code works. Making statements based on opinion; back them up with references or personal experience. For inputArray = [1, 1, 1], the output should be arrayChange (inputArray) = 3. Each year your balance increases at the same growth rate. This becomes a bit troublesome if you also allow "virtual clicks", as we find out later in the method. Why is "1000000000000000 in range(1000000000000001)" so fast in Python 3? We plant the seed at the beginning of a day. Last night you had to study, but decided to party instead. The game rushes to a finish when flagging the correct tile, it doesn't leave the user in suspense whether they have chosen correctly or not. Ideally, you would add a link to the pull request / code review / bug ticket where this issue is discussed in greater detail and maybe a link to a wiki page with a detailed explanation. You are given an array of integers representing coordinates of obstacles situated on a straight line. okay, I'll do this action then". Also, mentioning that you know one or two patterns during your interview (you should know them well enough to write them on a whiteboard) can make you stand out from the crowd. I would certainly perform a clear split between setting up the board and playing the game. No effort is needed to handle this case, as all we need to do is alter the displaying value. Avoid global s. These helpfully often disappear naturally when using OO. The knight can move to a square that is two squares horizontally and one square vertically, or two squares vertically and one square horizontally away from it. Can I tell police to wait and call a lawyer when served with a search warrant? no, since [-1] is a valid index (counting from the right) ;-). You could just use 2D slicing (see the corresponding stackoverflow topic) and do. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. I get IndexError with this code. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Given the total number of rows and columns in the theater (nRows and nCols, respectively), and the row and column you're sitting in, return the number of people who sit strictly behind you and in your column or to the left, assuming all seats are occupied.
