编程挑战：实现选择排序函数让数据从小到大排列

```c /* 对长度为n的数组arr执行选择排序 */ void selectionSort(int arr[], int n) { int i, j, min_idx; for (i = 0; i < n - 1; i++) { min_idx = i; for (j = i + 1; j < n; j++) { if (arr[j] < arr[min_idx]) { min_idx = j; } } if (min_idx != i) { int temp = arr[i]; arr[i] = arr[min_idx]; arr[min_idx] = temp; } } } ``` ######[AI问答 | 157点数解答 | 2025-12-09 19:06:49]
