This is one of the class coding problems from Programming job interviews. It may seem easy to reverse a linked list but when you go around doing the actual task, it's not that easy, especially for first-timers. There are a couple of algorithms exists to reverse a singly linked list in Java, like you can use the three-pointers approach or solve this problem using a Stack, or simply using Recursion without the external stack. As I had pointed out in the earlier post about the linked list, that reversing a linked list is one of the most popular linked list-based data structure interview question. This means, you just can't afford to prepare this one, before going for any programming interview. Despite being so common, It's not easy to solve this problem on the fly.​
