样例

#include <iostream>
#include <algorithm>
using namespace std;
int main() {
    int m, n, sum;

    cin >> m >> n;
    while ( m > 0 && n > 0 ) {
        sum = 0;
        if ( m > n ) swap(m, n);
        for ( int i = m; i <= n; i ++ ) {
            cout << i << " ";
            sum += i;
        }
        cout << "Sum=" << sum <<endl;
        cin >> m >> n;
    }

    return 0;
}
