C++实现花园花朵浇水次数统计

```cpp #include <iostream> #include <vector> using namespace std; int main() { int n, q; cin >> n >> q; // 用于记录每朵花被浇水的次数 vector<int> waterCount(n + 1, 0); // 进行q轮浇水 for (int i = 0; i < q; ++i) { int L, R, x; cin >> L >> R >> x; // 从第L朵花到第R朵花，每朵花浇x次水 for (int j = L; j <= R; ++j) { waterCount[j] += x; } } int start, end; cin >> start >> end; int sum = 0; // 计算指定区间内每朵花被浇水次数之和 for (int i = start; i <= end; ++i) { sum += waterCount[i]; } cout << sum << endl; return 0; } ``` ######[AI问答 | 262点数解答 | 2026-02-27 21:46:44]
