Final Solution

This problem is straightforward. We simply iterate over the integers $a_1, \dots, a_n$ and store their sum in a variable sum, that is initialized with $0$.

Code

#include<iostream>

int main() {
  std::ios_base::sync_with_stdio(false);
  
  int n_tests; std::cin >> n_tests;
  while(n_tests--) {
    int n; std::cin >> n;
    
    // Accumulate the sum of the integers while reading them
    int sum = 0;
    for(int i = 0; i < n; ++i) {
      int a; std::cin >> a;
      sum += a;
    }
    
    std::cout << sum << std::endl;
  }
}
