希尔排序——Python实现

      希尔排序思想请参见：https://www.cnblogs.com/luomeng/p/10592830.html

二、python实现

def shellSort(arr):
    """
    python希尔排序
    :param arr: 待排序列

    step :步长值
    """
    step = len(arr) // 2
    while step > 0:
        for rightIndex in range(step, len(arr)):
            while rightIndex >= step and arr[rightIndex] < arr[rightIndex - step]:
                arr[rightIndex - step], arr[rightIndex] = arr[rightIndex], arr[rightIndex - step]
                rightIndex -= step
        step //= 2


nums = [5, 6, 7, 2, 1, 65, 21, 22, 8, 0, 1]

shellSort(nums)

print(nums)
