Now, start popping the elements from the stack and iterating through the linked list together, and change the values in the nodes by the values we get from the stack.Now, after the iteration is complete, the linked list is stored in reverse order in the stack.Without wasting any more of your time, here is our complete Java program to solve this problem in one pass.

Iterate through the linked list and push the values of the nodes into the stack. How to find Kth Node From the End in a Linked List.pop (): Return the top object from the stack, and remove as well. The following methods we plan to implement as part of our stack implementation in Java using linked list. If yes, then no need to reverse it and simply return from the function. A stack by definition supports two methods, one is push for adding objects to the stack, and second, pop for removing the latest added object from the stack.

Check if the linked list is empty or has a single node.In all other cases, we need to reverse the linked list. In case, the linked list is empty or has only one node, reversing the linked list won’t make any change. So, due to its LIFO property, a stack is able to store elements in reverse order of their insertion and hence can be used to solve our problem.Ĭan you think of a case where we don’t need to reverse a linked list? And similarly, if we remove elements from the stack, we will get them in the reverse order of insertion. This means the element inserted at the last will be accessible to us. It follows the LIFO(last in first out) principle. We will look for that under Approach section.

Now, the main question is how to use a stack to reverse a linked list? pop () : This function should return and remove data in LIFO manner. You have to implement the following functions using a linked list which follows the LIFO property of stack : push () : This function should accept data in LIFO manner. In this problem we are given a singly linked list and we have to reverse it using a stack. You have to implement the LIFO property of stack using the linked list data structure.
