Can anyone explain the difference?

Hi!

I have two really similar submissions to problem (https://mirror.codeforces.com/contest/1266/problem/E)

https://mirror.codeforces.com/contest/1266/submission/67209030

https://mirror.codeforces.com/contest/1266/submission/67209163

The WA version has the following line:

long long ans = accumulate( a.begin(), a.end(), 0, [] (long long a, long long b) { return a + b; } );

On the AC version, the only change made was this one...

long long ans = accumulate( a.begin(), a.end(), 0ll, [] (long long a, long long b) { return a + b; } );

Why the first one doesn't seem to store the accumulated value in a long long?
