![]() I want to print the whole linked list but my display function print only 4. While (pointerNode != null & pointerNode.The void reve(struct Node *head) and display(struct Node *head) methods take one argument - the head of the linked list. Throw new IndexOutOfBoundsException("Index not available.") set node of left nose as newly created Node. set node of newly created node as right node. get the node at (index-1) from linked list and mark as leftNode. get the node at (index) from linked list and mark as rightNode. Public void add(T data, int index) throws IndexOutOfBoundsException else if (index newNode = new Node(data) * if index =0, element will be added at head and element become the first If index is negative value, nothing will be added to linked Index start from 0 to n-1 where n=size of Pop the data from Stack and add it to linked list The top most node in the stack always contains null in its address field. Stack is said to be overflown if the space left in the memory heap is not enough to create a node. We have given the head of a singly linked list, reversed the list, and returned the reversed list. Each node contains a pointer to its immediate successor node in the stack. Push all node to Stack starting from root In linked list implementation of stack, the nodes are maintained non-contiguously in the memory. * Reverse the linked list by reversing the pointers in reverse direction Result = prime * result + ((node = null) ? 0 : node.hashCode()) Result = prime * result + ((data = null) ? 0 : data.hashCode()) Now, we will have these two algorithm implementation in JAVA. 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. Reversing of linked list In here we are using the concept that stack uses LIFO that is Last In First Out.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.
