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:keyandrev
How to implement five different sorting algorithms in Python What the pros and cons are of using different algorithms You also learned about different techniques such as recursion, divide and conquer, and randomization. These are fundamental building blocks for solving a long list of different algorit...

Write a Python program to sort a list of elements using Comb sort. The Comb Sort is a variant of the Bubble Sort. Like the Shell sort, the Comb Sort increases the gap used in comparisons and exchanges. Some implementations use the insertion sort once the gap is less than a certain amoun...
1028. List Sorting Excel can sort records according to any column. Now you are supposed to imitate this function. Input Each input file contains one test case. For each case, the first line contains two integers N (<=100000) and C, where N is the number of records and C is the ...
