First you create a list of indices, set the mines and then.. setAdjacentMines - why? They should really have more intention-revealing names. The function 'show_mines()' is responsible for it. [input] string s1 probe would maybe be a better name. The function is clearly separated into a series of steps: setup, game loop, finish. A good example is a set of code checking every minute "is it now 7am?" moves required to obtain a strictly increasing sequence from the input. [input] integer deposit This allows you to make various MineBoard methods less complex, for example: In all other places, you use row and column indexing, but in this method you're using an index. The third candidate can win even if none of the remaining candidates vote for him. 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. This is especially true for environments that allow for reordering or refactoring of methods. This should definitely be in a separate method.

Why is "1000000000000000 in range(1000000000000001)" so fast in Python 3? The first one should probably just be MineBoard's __str__ method, and the second one should probably be part of the game logic rather than the board logic. A non-empty array of integers, sorted in ascending order. Given a string, check whether it is beautiful. 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. MathJax reference. All that said, after I concluded the review I understood the class design and would be able to alter it. [input] array.integer a The cell has already been flagged or not.

Refactoring covers not only lines of code into a function, but of data objects into different structures. It is guaranteed that the first two characters, as well as the last two characters, are digits. I get IndexError with this code. Python famously has a concept of DRY (Don't Repeat Yourself), which means that when you're starting to see multiple calls to a function, or repeating the same lines, that there is an opportunity for refactoring. Alternately, you. This is a collection of solutions for the code challanges in CodeFights/CodeSignal in C#. A tag already exists with the provided branch name.

For instance, it would allow you to flag already revealed positions, or maybe call setMine after the setup stage. I could guess the w and h, but how could a caller know that k is the number of mines? Here's the rooms matrix with unsuitable rooms marked with 'x': [input] array.array.integer matrix Consider integer numbers from 0 to n - 1 written down along the circle in such a way that the distance between any two neighbouring numbers is equal (note that (0 and n - 1 are neighbouring, too). This can be done by: In the code, we choose a random number from all possible cells in the grid. This abstraction would also allow us to move some of the methods out of MineBoard. In our version of Minesweeper, we will be using the row and column numbers for our input technique. CodeSignal is a skills-based assessment platform whose mission is to discover, develop and promote technical talent.
