Output

Enter the data item

5

Do you want to continue (Type 0 or 1)?

0

Status of the linked list is

5=>NULL

No. of nodes in the list = 1

Enter the data item

5

Do you want to continue (Type 0 or 1)?

1

Enter the data item

9

Do you want to continue (Type 0 or 1)?

1

Enter the data item

3

Do you want to continue (Type 0 or 1)?

0

Status of the linked list is

5=>9=>3=>NULL

No. of nodes in the list = 3
