巧用滑动窗口：求解给定正整数的连续正整数段之和

```python n = int(input()) # 使用滑动窗口 left, right = 1, 1 current_sum = 0 while left <= n // 2 + 1: if current_sum < n: current_sum += right right += 1 elif current_sum > n: current_sum -= left left += 1 else: print(f"{left} {right - 1}") current_sum -= left left += 1 ``` ######[AI问答 | 107点数解答 | 2026-01-04 12:15:55]
