计算歌曲美妙度：C++快速求最大值与最小值之比

```cpp #include <iostream> #include <algorithm> #include <iomanip> using namespace std; int main() { int n; cin >> n; int a[100]; for (int i = 0; i < n; i++) cin >> a[i]; int maxVal = *max_element(a, a + n); int minVal = *min_element(a, a + n); cout << fixed << setprecision(1) << (double)maxVal / minVal << endl; return 0; } ``` ######[AI问答 | 136点数解答 | 2026-03-22 17:33:31]
