Sum of the first N numbers using std::accumulate

C++ Easy STL

Task «Sum of the first N numbers using std::accumulate»

Write a program that reads a natural number N, then N integers, and outputs their sum. Use the std::accumulate algorithm from the STL to compute the sum. Input data: the first line contains an integer N (1 ≤ N ≤ 1000), the second line contains N integers separated by spaces. Output a single integer — the sum of the entered numbers.

Input Format

Integer N, then N integers separated by spaces.

Output Format

One integer — the sum.
