解决多次检测整数序列区间和问题的C++代码

```cpp #include <iostream> using namespace std; const int MAXN = 100005; int a[MAXN], sum[MAXN]; int main() { int n, m; cin >> n >> m; for (int i = 1; i <= n; i++) { cin >> a[i]; sum[i] = sum[i - 1] + a[i]; } for (int i = 0; i < m; i++) { int k; cin >> k; cout << sum[n] - sum[k - 1] << endl; } return 0; } ``` ######[AI问答 | 176点数解答 | 2026-05-30 19:33:47]
