a[x][y] is a 2D array and a[x] is a pointer pointing to the base address of an array and pointer subtraction is not allowed

You need to brush up your concepts of 2-D array. It seems that you are new to this thing, so try practicing the tutorial at hackerrank first. Also, google the usual required syntax and uses.

please provide the link to the problem. It’s really hard to figure out the error without looking at the problem question

Also, format the code or give an ideone link.
