Insertion Sort Using Linked List

Write a Program to implement c Insertion Sort Using Linked List. This tutorial is intended to provide you information about what insertion sort algorithm is and how to implement it in programming rather than it’s technical stuff, properties and comparision with other sorting algorithm.

This is an in-place comparison-based sorting algorithm. Here, a sub-list is maintained which is always sorted.

For example : The lower part of an list is maintained to be sorted. An element which is to be ‘inserted in this sorted sub-list, has to find its appropriate place and then it has to be inserted there. Hence the name, insertion sort.

The array is searched sequentially and unsorted items are moved and inserted into the sorted sub-list). This algorithm is not suitable for large data sets as its average and worst case complexity are of Ο(n2), where n is the number of items.

Below is simple insertion sort algorithm for linked list.

1) Create an empty sorted (or result) list

2) Traverse the given list, do following for every node.

……a) Insert current node in sorted way in sorted or result list.

3) Change head of given linked list to head of sorted (or result) list.

Below is the source code for C Program to implement Insertion Sort Using Linked List which is successfully compiled and run on Windows System to produce desired output as shown below :
