The insertion sort algorithm works by iterating through the list and inserting each element into its correct position in the sorted portion of the list. 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 + ...

Python has two basic function for sorting lists:sortandsorted. Thesortsorts the list in place, while thesortedreturns a new sorted list from the items in iterable. Both functions have the same options:keyandreverse. Thekeytakes a function which will be used on each value in the list being ...

插入排序(Insertion Sort)是一种简单但有效的排序算法,它的基本思想是将数组分成已排序和未排序两部分,然后逐一将未排序部分的元素插入到已排序部分的正确位置。插入排序通常比冒泡排序和选择排序更高效,特别适用于对部分有序的数组进行排序。本文将详细介绍插入排序的工作原理和Python实现。
定义函数:我们定义了一个名为insertion_sort的函数,接收一个列表arr作为参数。 遍历数组:使用for循环从数组的第二个元素开始遍历。 记录当前元素:将当前元素(即需要插入的那个元素)存储在key变量中。 比较并插入: 使用while循环比较key和已排序部分的元素,若已排序元素大于key,则将其后移。
Original list: (1.1, 1, 0, -1, -1.1) After applying Timsort the said list becomes: [-1.1, -1, 0, 1, 1.1] Flowchart: For more Practice: Solve these Related Problems: Write a Python program to sort a list using Timsort and then output the detected runs during the sorting proc...
