Another approach rather than my approach to generate the prefix sum
I solved this problem by using the prefix sum method.But as an output i am either getting a negative sum or a very huge sum.
hello @Varun_a19
handle the corner case
ie when i=0 or j=0 then remove all those term which uses i-1 or j-1.
