Implement these functions in your linked list class: get(index) : Get the value of the index-th node in the linked list. If the index is invalid, return -1. addAtHead(val) : Add a node of value val before the first element of the linked list. After the insertion, the new node ...

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.It repeats until no input elements remain. Example 1: Input: 4->2->1->3Output: 1->2->3->4Example 2: Input: -1->5->3->4->0...

Design your implementation of the linked list. You can choose to use a singly or doubly linked list.
