ALGORITHM (Insertion of element into a linked list)

Step 1 Begin the program

Step 2 if the list is empty or any new element comes before the start (head) element, then add the new element as a start element.

Step 3 else, if the new element comes after the last element, then add the new element as the end element.

Step 4 else, add the new element in the list using the determinefunction,determine function returns the address of the found element to the insert_list function.

Step 5 End.

Figure demonstrated the scenario of a linked list of two elements & a new element that has to be inserted between them. Figure demonstrate the scenario of a linked list after insertion of any new element into the linked list of Figure.

Before insertion

Figure: A linked list of two elements & an element that is to be inserted

After insertion

Figure: Insertion of a new element into linked list

Program demonstrated the code for the insertion of any element into linked list by searching for the position of insertion alongwith the help of a find function.
