![]() Here previous will be the last node in linked list. Finally, set next node of previous node as NULL.Set next node of previous node as current.pop the node from stack and assign to current.Repeat steps 5, 6 and 7 till stack is not empty.Create 2 node variables, previous and current and assign as root node.Pop the top node from stack and assign it to root.clear the linked list by updating the reference of root as null.Now, Stack has all the nodes where root node at bottom and rear node at top.Clear the linked list and pop the nodes from stack and update the pointers. assign current as next node of current node.Repeat steps 3 and 4 till current node is not null.Create node variable, current and assign the root node. Put the nodes of linked list starting from root node to Stack. Reverse using Stack : Now, we will see the algorithm to reverse a singly linked list using Stack.See the below steps and execution process. assign the root node as previous, root=previous.Repeat steps 3, 4 and 5 till current != null.Declare 3 node variables, current, previous, next and initialize current=root node.This is very common algorithm to reverse the singly linked list.Apart from this, we will see the other algorithm where we will reverse a singly linked list using Stack.īy reversing the pointers : See the below algorithm and their execution process. We can reverse a singly linked list by reversing the pointers in reverse direction. In previous post, we saw the methods to get the data based on index and get the index of data in linked list.In this post, we will see the algorithm to reverse a singly linked list and implement in JAVA.ġ.
