C++实现多组整数求和查询问题

```cpp #include <iostream> #include <vector> using namespace std; int main() { int n, m; cin >> n >> m; // 存储数组a vector<int> a(n + 1); for (int i = 1; i <= n; i++) { cin >> a[i]; } // 存储询问的k值 vector<int> k(m); for (int i = 0; i < m; i++) { cin >> k[i]; } // 处理每次询问 for (int i = 0; i < m; i++) { int sum = 0; for (int j = k[i]; j <= n; j++) { sum += a[j]; } cout << sum << endl; } return 0; } ``` ######[AI问答 | 221点数解答 | 2026-05-30 20:44:31]
