Segregate Node Of Linkedlist Over Pivot Index

medium

1. Given a singly linklist, Segregate Node of LinkedList over pivot index and return starting node of linkedlist. 2. pivot will be any random index in range of 0 to length Of Linkedlist 3. After segregation pivot Element should have to be present at correct position as in sorted linkedlist.

Constraints

-10^6 <= size Of LinkedList <= 10^6 0 <= pivot Index <= 10^6
