linked lists operations code example

Example: linked list operations

// the function is returning the head of the singly linked list
Node insertAtEnd(Node head, int val)
{
    if( head == NULL ) // handing the special case
    {
        newNode = new Node(val)
        head = newNode
        return head
    }
    Node temp = head
    // traversing the list to get the last node
    while( temp.next != NULL )
    {
        temp = temp.next
    }
    newNode = new Node(val)
    temp.next = newNode
    return head
}
