Confusion in using accumulate function

Revision en3, by chirag2505, 2021-08-30 14:07:00

Hello Codeforces!

I have a doubt in today contest problem A :(https://codeforces.net/contest/1557/problem/A)

I submitted solution in which I have used accumulate function to get sum of all elements of vector but it gave me WA.

And finally I got AC in which I find sum by traversing all elements.

Is there any difference in both methods to get sum of all elements of vector?

Here are the links of my both submissions :

125393659 — WA

125396830 — AC

Please help me to find out the error in code(using accumulate function).

Thanks in advance:)

UPD : Resolved
