Selection sort using linked list

Selection sort is a sorting algorithm that works by repeatedly finding the minimum element from an unsorted list and moving it to the beginning of the list. This process is repeated for each element in the list until the entire list is sorted.

When implementing selection sort using a linked list, the idea is to traverse the linked list, find the minimum element from the remaining unsorted part of the list, and move it to the beginning of the list by changing the pointers.

Here's an example of how selection sort using linked list works:

1. Start with the head of the linked list.
2. Traverse the linked list to find the minimum element from the remaining unsorted part of the list.
3. Swap the data of the current node with the minimum element found in step 2.
4. Move to the next node and repeat steps 2 and 3 until the end of the list is reached.

At the end of this process, the linked list will be sorted in ascending order. Selection sort using linked list has a time complexity of O(n^2), where n is the number of elements in the list.
