Tell - Don't Ask: When your code has a lot of if-this, then-that statements in it, it's clear the logic belongs with the data rather than continually asking the data "are you this?" This can be done by: In the code, we choose a random number from all possible cells in the grid.

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. It seems that a click is also opening mines around the clicked location. [input] string s1 In general, if you use two different ways to write the exact same thing, the reader will think that you want to convey a message with that. This course explores the concepts and algorithms at the foundation of modern artificial intelligence, diving into the ideas that give rise to technologies like game-playing engines, handwriting recognition, and machine translation. It could access Cell objects and -- when passed slices --- could even return an iterable over the Cells. However, it is also rather dangerous.

'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. These methods should definitely be private. Then you can use groups 1, 2 and 3 to retrieve the values. Another method is to have multiple layers, e.g. Thanks Felicity for your post.

A positive integer representing the nightly growth. 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.
