31. Reverse a Linked List Using Recursion

Objective: Reverse the given linked list using recursion

Example: 

Original List :->10->8->6->4->2
Reversed List :->2->4->6->8->10

Approach:

Recursion:

  • Traverse till the end of list through recursion.
  • Make the last node as head.
  • Now you are at the end of the list and rest of the nodes are stores in a stack
  • Now while coming back, each node will pop out from the stack in reverse order
  • take these nodes and start pointing it to next node coming out of stack.

->10->8->6->4->2
Reversed List :
->2->4->6->8->10
