python选择排序算法的特点

    if idx1 == idx2:
        return
    temp = nums[idx1]
    nums[idx1] = nums[idx2]
    nums[idx2] = temp
 
 
def select_sort(nums):

    选择排序，记录最小元素的索引，最后才交换位置

    l = len(nums)
    for i in range(l):
        min_index = i
        for j in range(i + 1, l):
            if nums[j] < nums[min_index]:
                min_index = j
        swap(nums, i, min_index)
