what is Tim-sort?

11:27 PM
Tim-sort Tim-sort is a sorting algorithm derived from insertion sort and merge sort. It was designed to perform in an optimal way on different kind of real world data. It is an adaptive sorting algorithm which needs O(n log n) comparisons to sort an array of n elements. It was designed and implemented by Tim Peters in 2002 in python programming language. It has been python's standard sorting algorithm since version 2.3. Technique Consider an array of n elements which needs to be sorted. In Tim sort, the array is divided into several parts where each of them is called a Run. These Runs are sorted by using insertion sort one by one and then the sorted runs get combined using a combine function. The idea of Tim sort is originated from the fact that, insertion sort works more optimally on the short lists rather than working on the larger lists.
