Whats the issue with these builtin function in c++?
By srijon_32, history, 23 hours ago, In English

Here are my two submission for problem : 1158A - The Party and Sweets

  1. using accumulate function: 300047140

  2. using loop: 300047827

1st one giving wrong answer. Previously, the same thing happened with sqrt, and then I used binary search to find sqrt. So after this WA, I used a loop to get the sum, and now it's giving the correct answer. So where has this accumulate function gone wrong?

The initial value of the accumulate function must be a 64-bit data type; otherwise, an overflow will occur.

you need to declare initial value in accumulate function long long int if sum would needed long long int to fit in. Just simply use 0LL instead of 0

You have to use 0LL in accumulate function
