sir can you explain this with the help of dry run. Actually loops are not clear that how can we change the row.
2D array wave print
@vrcoolbuddy08 basically you have to go to every column from 0 to m-1 and if column no is even then you have to traverse up to down (0 to n-1) else if col odd (n-1 to 0)
you can do this using if else loop.
hope its clear if yes dont forget to hit like and mark resolved
