Hello @Vipul.kapoor,

In the question, you are required to find the kth element from the end of the linked list i.e. the right most node.

But, your code is printing the (k+1)th term from the head of the linked list.
Examples:

  1. 1 2 3 4 5 6 -1
    1
    Your Output:
    2
    Expected Output:
    6

  2. 1 2 3 4 5 6 -1
    2
    Your Output:
    3
    Expected Output:
    5

Correct it.
Hope, this would help.
Give a like if you are satisfied.
