3.(CSDN)C++,java,Python的内部实现sort怎么实现的:内容提到 python内部的sort采用的是混合(hybrid)排序,规模小的时候采用binary insertion,规模大的时候采用sample sort。 4.(流畅的python)list.sort 方法和 sorted 函数:注7 中提到 python的排序算法——Timesort——是稳定的,意思是就算两个元素比不出大小,在每...

Write a Python program to sort a list of elements using the insertion sort algorithm. Note : According to Wikipedia "Insertion sort is a simple sorting algorithm that builds the final sorted array (or list) one item at a time. It is much less efficient on large lists than more advanced ...
