Here is my solution to the problem. I am getting partial points. I have checked other submissions[1, 2] where there are printing sum of max no. of targets in a row and column.

But consider the case when targets in column and row coincide :

2 3 3

1 1

0 0

0 1

Both the codes print answer as 4, even if there are only 3 targets to destroy. Since there are 3 targets correct answer should be 3.

Does the problem has weak test cases or am I missing something crucial here?
