Insertion Sort ExampleThe following Python code demonstrates the insertion sort algorithm. insertion_sort.py def insertion_sort(arr): for i in range(1, len(arr)): key = arr[i] j = i - 1 while j >= 0 and key < arr[j]: arr[j + 1] = arr[j] j -= 1 arr[j + 1] = key ...
其工作原理是通过构建有序序列,对于未排序的数据,在已排序序列中从后向前比较,找到相应位置并插入。 时间复杂度 O(N2) ,但是根据输入数据的情况不同,其时间复杂度也不同,比如序列已经是一个排序好的序列,算法仅需遍历一遍序列,时间复杂度为O(N) 空间复杂度 O(1) python代码如下: definsertion_sort(nums):for...
