You can initialize a result matrix with a zero on "O" cells and "X" on the mine positions. On subsequent games, I failed again because of this input-handling problem. Thanks Felicity for your post. 'E' represents an unrevealed empty square, 'B' represents a revealed blank square that has no adjacent mines (i.e., above, below, left, right, and all 4 diagonals), digit ( '1' to '8') represents how many mines are adjacent to this revealed square, and 'X' represents a revealed mine. Do new devs get fired if they can't solve a certain bug? Does Python have a ternary conditional operator?

If the IDE doesn't highlight these, possibly change your IDE. [input] integer upSpeed I could guess the w and h, but how could a caller know that k is the number of mines? Permalink. 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. For example, if you pushed your script into the repository, and a code documentor such as Sphinx ran over it, it would freeze because it would start playing the game. Otherwise a[i] is the height of a person standing in the ith position. 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__. In fact, when you instantiate it, you actually assign it to a variable named game! Two cells are called neighboring if they share at least one corner.'''.

[input] string time This code works fine until bomb is in the last column of the matrix, for example: 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. This makes it hard to reuse and hard to test. The largest product of adjacent elements. In this article, we will be going through the steps of creating our own terminal-based Minesweeper using Python Language. F-strings: Python 3.6 and later have this capability; f-strings can make reading print statements much easier.

I hope the other answers as well as mine are enough to give you lots to study before your next interview. 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.

If there are several possible answers, output the smallest one. You can see the 1-, 2-, 3- and 4-interesting polygons in the picture below. Asking for help, clarification, or responding to other answers. This means we need to check at 8 spots for each cell: Top left, Top Middle, Top Right, Middle Right, Middle Left, Bottom Left, Bottom Middle, and Bottom Right. An example of what I mean is the print_layout method. On the completion of input process, the row and column numbers are to be extracted and stored in 'r' and 'c'. [input] array.array.integer image First, the string is divided into the least possible number of disjoint substrings consisting of identical characters, for example, "aabbbc" is divided into ["aa", "bbb", "c"], Next, each substring with length greater than one is replaced with a concatenation of its length and the repeating character, for example, substring "bbb" is replaced by "3b". Thank you in advance. Whenever a gamer, visits a 0-valued cell, all the neighboring elements must be displayed until a non-zero-valued cell is reached. You signed in with another tab or window. Given the positions of a white bishop and a black pawn on the standard chess board, determine whether the bishop can capture the pawn in one move.
