Checking Surrounding Squares for Number of Mines
|
Assume [R] [C] is the cell that needs to be checked for how many mines are around it. We then need to check from [R-1] [C-1] to [R+1] [C+1], keeping track of the number of mines around this cell. Then we need to store this value in [R] [C] . Note: this will only work for inside cells. Outer cells are a different case. |
Method for Checking around [R] [C]
- check to see if a mine is stored in R,C (if a mine is stored here, no need to proceed)
- check cell R,C to make sure it isn't an outer cell of the array (if it is, this is a different case)
- initialize a counter that keeps track of the number mines around R,C
- use a loop to traverse every cell around R,C (from R-1.C-1 to R+1, C+1)
- check each cell for a mine (if mine = true, then increase counter)
- loop until all surrounding cells have been checked
- store counter value in cell R,C of the array
