I am trying to write a recursive function
void check_array(int array1[M],int row,int col,int array1[row][col]);
(it might have to be an int function in the end)
The object of this function is check what number is in array1[row][col] and to printf how many similar neighbors it has.
if function is called with 2,2 then the number is 3 and it has 9 connected 3's
4 3 2 3 1
5 3 3 2 2
1 1 3 3 2
1 3 3 2 4
5 5 3 4 4
if function is called with 4,4 then the number is 4 and it has 3 connected 4's (the extra 4 in the array is not adjacent)
Now the catch is I need to do it recursively. Do you have any advice on how to approach the problem? I could use a helper sub-function if need be, I jsut have no idea how to approach this.
