C++实现查找小于等于指定值的最大电压信号

```cpp #include <iostream> using namespace std; int main() { int n; cin >> n; int signals[100000]; for (int i = 0; i < n; ++i) { cin >> signals[i]; } int k; cin >> k; for (int i = n - 1; i >= 0; --i) { if (signals[i] <= k) { cout << signals[i] << endl; return 0; } } return 0; } ``` ######[AI问答 | 162点数解答 | 2026-04-11 20:19:34]
