用数组 回答篇幅：简单明了

```cpp #include <iostream> using namespace std; int main() { int n; cin >> n; int blueNums[20]; for (int i = 0; i < n; i++) { cin >> blueNums[i]; } int redNum; cin >> redNum; int result = 0; for (int i = 0; i < n; i++) { if (blueNums[i] == 3 * redNum) { result += blueNums[i] * 3; } else if (blueNums[i] == 5 * redNum) { result += blueNums[i] * 5; } else if (blueNums[i] == 7 * redNum) { result += blueNums[i] * 7; } else { result += blueNums[i] * 11; } } cout << result; return 0; } ``` [2026-01-03 19:49:36 | AI问答 | 240点数解答]
