整数序列后缀和查询的代码实现

```cpp #include <iostream> using namespace std; int n, m, k; int a[100010], sum[100010]; //sum为后缀和数组 int main() { cin >> n >> m; for (int i = 1; i <= n; i++) { cin >> a[i]; } for (int i = n; i >= 1; i--) { sum[i] = sum[i + 1] + a[i]; } for (int i = 1; i <= m ;i++) { cin >> k; cout << sum[k] << endl; } return 0; } ``` ######[AI问答 | 190点数解答 | 2026-05-30 19:34:02]
