#include <iostream>


using namespace std;


long ans = 0;


int main()
{
    cout << "Enter an integer in the range of 1 to 10000 or -999 to quit\n";
    while (true) {
        long n;
        cin >> n;
        if (n == -999) {
            cout << ans;
            break;
        }
        ans += n;
    }
    return 0;
