用C++破解梯子密码锁的数字求和问题

```cpp #include <iostream> using namespace std; // 计算从1到num的和 int sumFromOne(int num) { return num * (num + 1) / 2; } int main() { int n; cin >> n; int m[100]; for (int i = 0; i < n; i++) { cin >> m[i]; } for (int i = 0; i < n; i++) { cout << sumFromOne(m[i]); if (i < n - 1) { cout << " "; } } cout << endl; return 0; } ``` ######[AI问答 | 185点数解答 | 2026-03-28 19:54:28]
