# Find the kth to last element of a singly linked list

#### Problem description :

Implement a **non-recursive** algorithm to find the **kth to last element** of a singly linked list.

**Input :** A linked list

**Output :** A value of a node in a linked list

#### Logic :

- Iterate through the list with two pointers
`p1`

,`p2`

. `p2`

is`k`

steps ahead of`p1`

.- When
`p2`

is at the end of linked list`p1`

is at the`kth`

to last element of a singly linked list.

This post is a follow-up of JavaScript Linked List Example. I recommend reading that first, as the following code uses the method from it.
