Hi guys can someone please help me out. I’m getting correct output for the sample input but still getting WA.

How did you even come up with this? There are more cases that this program will get wrong than right. Why sum - 1? How does the sorting relate to the fact that you have to go right or stay on the same column?

I tried solving some cases myself both sorted and unsorted and I noticed that answer was always 1 less than that from the sorted array. So sum-1 :confused: . Also, I’m new to this :slightly_frowning_face:

I mean… any case where all the numbers are equal

Yeah in that case it fails. Thanks.
