A non-empty rectangular matrix consisting of boolean values - true if the corresponding cell contains a mine, false otherwise. 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. A book called "Code Complete" can be useful in learning different patterns of common mistakes made by programmers, I recommend grabbing a copy.

Given an array of integers, find the maximal absolute difference between any two of its adjacent elements. Given a string, output its longest prefix which contains only digits. 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. This repository includes my solutions for the arcade challenges in CodeSignal. Some rooms are free (their cost is 0), but that's probably because they are haunted, so all the bots are afraid of them.

Python 3: Solving arrayChange in CodeFights - Stack Overflow Minesweeper is a puzzle video game. 72 stands for H in the ASCII-table, so the first letter is H. Here's my proposal: (I like using dataclasses for things like this, but of course there are plenty of other options, like attrs or a plain Python class!). After we land on a cell with mine, we need to display all the mines in the game and alter the variable behind the game loop. The digits sum up to 0 + 4 + 0 + 0 = 4, which is the answer. The idea to have one board with an integer to represent states is a nice idea. They should be called _ to make clear that they are deliberately ignored: All the elifs can just be ifs, since in all of the conditionals in this method, we either exit the method or the conditional was false. This should definitely be in a separate method. Aftermath of few hours of creating a game of Minesweeper. It's clear that an enum for state and data is needed per tile, as well as the tile having the capability of call-backs into the board say when a mine was triggered.
