C program to count number of nodes of a Singly Linked List. Algorithm to insert node at the beginning of a linked list. Insertion in doubly linked list after Specified node. C program to delete all nodes of a Singly Linked List. Algorithm. The list initially contains 3 nodes. And the new node will point where head was pointing to before insertion. just after 2 nd position. 2) If the value of the node to be inserted is smaller than the value of the head node, then insert the node at the start and make it head. C program to reverse a Singly Linked List. Imagine our linked list is not necessarily sorted and there is no reason to insert a new node in any special place in the list. Create a newNode and assign some data to its data field. If the head node is Null, then insert the data in the head node. We will follow below steps to insert node at 2 nd position in the list. Allocate the memory for the new node. Create a new node… 1) If Linked list is empty then make the node as head and return it. Then we have an easiest place to insert the node is at the beginning of the list. Algorithm: Let input linked list is sorted in increasing order. A Linked list is a linear data structure which consists a group of nodes and each node points to next node by means of a pointer. Here is a C program to insert an element in a linked list An algorithm that does so follows. C program to insert a node at the beginning of a Singly Linked List. 2. In order to insert a node after the specified node in the list, we need to skip the required number of nodes in order to reach the mentioned node and then make the pointer adjustments as required. Steps to insert new node in a Circular linked list. Use the following steps for this purpose. Head of a linked list always points to the first node if there is at least one element in the list. Algorithm of insertion at the beginning. Create a new node dynamically (by allocating a memory). There are three different types of insertions that you have to code for: [code ]insertFirst[/code], [code ]insertBefore[/code] and [code ]insertAfter[/code]. A Linked list consists of a set of nodes and each node has some data and a pointer to next node. Insert New Element at the Front of the Linked List. So inserting a new node means the head will point to the newly inserted node. In Linked list, a node consists of two parts, a data and a pointer to next node.
