Error in template

The last argument in accumulate (i.e. 0 in this case) should have same data type as that of array. So the following code fails (gives compilation error)

vector<long long int> v = {1, 3};
cout << accumulate(v.begin(), v.end(), 0) << '\n';

while the following passes

vector<long long int> v = {1, 3};
cout << accumulate(v.begin(), v.end(), 0LL) << '\n';

In template, we are accepting the type of elements that vector contains, but using accumulate as if vector contains only integers.

@harshraj22 Oh, got it, thanks for pointing this out, can you find a fix for this?

Somehow the template seems to be working, which I can't figure out why. Hence closing.
