# Reverse a singly linked list

#### Problem description :

Write a function to reverse a singly linked list.

**Input :** A linked list

**Output :** A linked list

#### Logic :

- Iterate through linked list with three-pointers
`previous`

,`current`

,`next`

. - While iterating at each step reverse the current link’s direction.

#### Time Complexity :

**O(n)**; where n is the number of nodes in the 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.

This post is a pre-requisite for Given a singly linked list find if it is palindrome. I recommend reading this first, before going to the palindrome post.
