insertion sort linked list java

The steps of the insertion sort algorithm: Insertion sort iterates, consuming one input element each repetition and growing a sorted output list. Merge Sort works by breaking the linked list(or Array) into 2 equal parts say Left half and Right half. The return value is an * array where the [0] element is a head reference for the copy and the [1] * element is a tail reference for the copy. Sometimes it will sort successfully and sometimes it don't. At each iteration, insertion sort removes one element from the input data, finds the location it belongs within the sorted list and inserts it there. Given a linked list, the task is to sort the linked list in ascending order by using selection sort. The second element is compared with the first and swapped if not in order. In-Place Insertion Sort. In the next section, let’s switch from arrays and use the technique to sort the linked list and array list data structures.
