NettetReverse a doubly linked list In this post, we will see how to reverse a doubly linked list using iteration and recursion. Practice this problem 1. Iterative Solution The idea is simple – Traverse the list and swap next and prev pointers for each node. Finally, update head pointer to point to the last node. Nettet2. des. 2024 · Reverse a stack using Recursion The idea of the solution is to hold all values in Function Call Stack until the stack becomes empty. When the stack becomes empty, insert all held items one by one at the bottom of the stack.
