[input] string inputString [input] integer yourLeft On the completion of input process, the row and column numbers are to be extracted and stored in 'r' and 'c'. Aftermath of few hours of creating a game of Minesweeper. I am not a big fan of mixing I/O and computation. No catching/handling of exceptions raised e.g. @KennyOstrom I don't see an issue with it. Given an integer product, find the smallest positive (i.e. A string consisting of lowercase English letters. There was a problem preparing your codespace, please try again. Your task is to find the area of a polygon for a given n. A 1-interesting polygon is just a square with a side of length 1. The function 'show_mines()' is responsible for it. The players motive behind this move is to unlock a cell that does not contain a mine. The terminal becomes crowded as we keep on printing stuff on it. (OTOH, it is tremendously helpful if you have them turned on from the start, since you will be immediately notified and can thus avoid letting the count ever get this high.). Gameplay Demo Aftermath of few hours of creating a game of Minesweeper. 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. You can initialize a result matrix with a zero on "O" cells and "X" on the mine positions. You have deposited a specific amount of dollars into your bank account. Each year the amount of money on your account increases by 20%. Two arrays are called similar if one can be obtained from another by swapping at most one pair of elements in one of the arrays. Does Python have a string 'contains' substring method? Do you see how this might be confusing to someone that is reading your code? The same applies to the game loop itself, it also has distinct steps. [input] string time 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. The use of variables like, mine_values will be explained further in the tutorial. After all the cells with zero value and their neighbours are displayed, we can move on to the last scenario. Return true if it is possible to remove one element from the array in order to get a strictly increasing sequence, otherwise return false. [input] integer friendsLeft We count the number of cells, that are not empty or flagged. Avoid global s. These helpfully often disappear naturally when using OO. As I said, using exceptions as normal control is a bad idea in most languages, python being an exception. I just reversed your logic: I walk through the output field and add values from matrix. And I get the code formatted according to my preferences (e.g. For all problems, the following libraries are considered to be automatically imported: import math import string import re import random import functools About How many neighbours of this cell are mines? Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Note that there are only two items and you can't bring more than one item of each type, i.e. It's recommended to use them when writing any string statement that contains variables. It results in more readable code and a more logical flow than checking the bounds every time. When needing user input, ensure it's specific, that it's limited, and that you give responses to assist the user to provide the correct input, or allow them to exit the stage where they are.This will enable avoiding runtime errors which crash the program (such as IndexError list assignment index out of range which I encountered) and avoid having try/except/finally statements due to limiting possible inputs. Making statements based on opinion; back them up with references or personal experience. The two equal numbers are a and c. The third number (b) equals 7, which is the answer. Therefore, there must be provision for clearing it constantly. numCount = 0. mainList = [] # main board for the game. All in all, it doesn't adhere to the principle of least surprise to me. Your task is to check by given string inputString whether it corresponds to MAC-48 address or not. In fact, when you instantiate it, you actually assign it to a variable named game!

A constraint satisfaction problem has a few parts: A set of variables. A big clue is the fact that you have multiple comments talking about "cells" but you have no abstraction called "cell" in your code. Given your and your friend's arms' lifting capabilities find out if you two are equally strong. When this count is equal to the total cells, except those containing mines, then the game is regarded as over. then count the number of Xs in the merged tuples: This runs roughly 5x faster than the index/offset based solution. You are given an array of positive integers - the weights of the people. This might be a little extensive, but it's good to make you aware of what could be covered when submitting code during the interview process. Personally I don't like it when click hides other functionality, I'd put that in a calling function. To reach the next level your XP should be at least at threshold. Remove the import. 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. Learn more about bidirectional Unicode characters. A tag already exists with the provided branch name. Check if the given string is a correct variable name. An IP address is a numerical label assigned to each device (e.g., computer, printer) participating in a computer network that uses the Internet Protocol for communication. I hope the other answers as well as mine are enough to give you lots to study before your next interview. Funny that we came to the dual layer / dual classes approach seperately. to use Codespaces. Starting off with some arrangement of mines we want to create a Minesweeper game setup.. Minesweeper is a single-player game in which the player has to clear a square grid containing mines and numbers. 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. You signed in with another tab or window. How to follow the signal when reading the schematic? And then in play, the two calls to game.print_layout() can simply be replaced by print(game). Find out how long it would take for your balance to pass a specific threshold with the assumption that you don't make any additional deposits. rev2023.3.3.43278. Not the answer you're looking for?

I gave an example on how to remove the border without using pop() in my answer. Ow, I wonder how you would reveal those mines. February 7, 2022 . A string containing at least one digit. This can be done by: Note: There is a need to import the os library, before using this feature. 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. [output] boolean 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. We need to set up the positions of the mines randomly, so that the player might not predict their positions. topic page so that developers can more easily learn about it. A non-empty rectangular matrix consisting of boolean values - true if the corresponding cell contains a mine, false otherwise. Some whitespace would help draw attention to those steps: Actually, it would make even more sense to extract the various separate steps into separate functions. pip3 install -r requirements.txt. Do read comments as they explain a lot and also every block of code. The cells are opened when clicked and if the user clicks on a cell holding a mine then the user loses. Two cells are called neighboring if they share at least one corner.'''. One which just creates the string representation of the board, and a second one which prints it. sign in For the first example below, the output should be true. The neighbours function is a recursive one, solving our problem. Why are non-Western countries siding with China in the UN? Rather than doing that, the set_alarm(self, hour, minute) function would spawn a thread which waits for hour/minute and then activates a call-back to the activate_alarm(self) function. It is needed to update every move of the player as well as the conclusion of the game. A positive even integer. What is the value of the third integer? 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. is unnecessary.

A media access control address (MAC address) is a unique identifier assigned to network interfaces for communications on the physical network segment. For any queries, feel free to comment below. If your code is so complex that you need to explain it in a comment, you should rather try to refactor your code to be less complex so that it needs no explanation. A string consisting of lowercase latin letters. If nothing happens, download Xcode and try again. Then you can use groups 1, 2 and 3 to retrieve the values. For the other grid, the output should be false: each of the nine 3 3 sub-grids should contain all of the digits from 1 to 9. As we can see clearly, any number on the grid denotes the number of mines present in the neighbouring eight cells. The variables are the board squares, which each contain either a mine or a constant between 0 and 8. I'm doing codefight's challange: minesweeper. Find the longest word from the given string.

There are a couple of names in your code that could be clearer, for example ip, m, and k. In particular, it seems that the parameter k in __init__, the parameter num_of_mines in allocate_mines, and the local variable m in play mean the same thing, but the parameter k in get_random_pos does not mean the same thing as the parameter k in __init__. But I honestly don't see why they exist at all, in that case.

In your efforts to find a clue, you've found a binary code written on the wall behind a vase, and realized that it must be an encrypted message. 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. The description: The border created by "x", as suggested by codefight's user, is to ensure that if mine is at the border of matrix, bomb count won't transfer to the other side. Your code is all bunched up together. Is a collection of years plural or singular? The role of vis to keep track of already visited cells during recursion. Enum for GameStatus but then not using the same logic with tile values? For this particular concept of the game, a new data structure is used, namely, vis. All of them are fully functional. The rest of it is your good old basic minesweeper. Then a nested loop on each position can go through the offsets to add 1 to the 'zero' cells when the neighbouring position is in range of the board and contains an "X": If you want to avoid messing with indexes and offsets, you can prepare 8 shifted copies of the board (one per direction) and use zip() to combine them into a tuple of neighbours for each position. It is guaranteed that parentheses form a regular bracket sequence. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. I like the way the status is explicitly kept using the enum; it makes everything that more easy to follow. You are playing an RPG game.
