Example of Doubly linked list in C There are various operations that can be performed in the Doubly Linked List: Insertion: Insertion of node at the beginning of the list. Insertion of node at the end of the list Insertion of node at a particular position in the list (before/ after a g...
} //insertion at the beginning void insertatbegin(int data){ //create a link struct node *lk = (struct node*) malloc(sizeof(struct node)); lk->data = data; // point it to old first node lk->next = head; //point first to new first node head = lk; } void insertatend(int ...
Insertion at the beginning Insertion in-between nodes Insertion at the End Suppose we have a double-linked list with elements 1, 2, and 3. Original doubly linked list 1. Insertion at the Beginning Let's add a node with value 6 at the beginning of the doubly linked list we made above...
Insertion at the beginning Insertion in-between nodes Insertion at the end Suppose we have a circular linked list with elements 1, 2, and 3. Initial circular linked list Let's add a node with value 6 at different positions of the circular linked list we made above. The first step is ...
Insertion in a Linked ListInserting element in the linked list involves reassigning the pointers from the existing nodes to the newly inserted node. Depending on whether the new data element is getting inserted at the beginning or at the middle or at the end of the linked list, we have the...
covered many sorting algorithms, and we could do many of these sorting algorithms on linked lists as well. Let's take selection sort for example. In selection sort we find the lowest value, remove it, and insert it at the beginning. We could do the same with a linked list as well, ...
For insertion in the list at the beginning, we created a node t and in its data part, we named it as x. Therefore, if the start is null then start will be put in node t data part and the address part will point to the next part which is NULL. This process will insert the elem...

The linked list can be empty before insertion. We have to insert an element at the beginning of a non-empty linked list. We have to insert an element at the end of a linked list. We have to insert an element at a given position in the linked list. Let us discuss how to insert an...
1) Inserting at the beginningIn this case, a new node is to be inserted before the current head node, i.e. , every time the node that got inserted is being updated to the head node. Such insertion can be done using following steps....
