Sum of N integers

You are given $N$ integers. Write a program that computes the sum of those $N$ integers.

When $N$ and every integer are at their largest, the sum is $3{,}000{,}000{,}000{,}000$, so a 32-bit integer type cannot hold the answer. Use a 64-bit integer type.

The first line has the number of integers $N$ ($1 \le N \le 3{,}000{,}000$).

The second line has the $N$ integers, separated by single spaces. Each integer is between $0$ and $1{,}000{,}000$.

Print the sum of the given $N$ integers on the first line.
