1. You are given a linked list with N nodes.
2. The linked list contains data values as 1 or O only.
3. You have to write a function that returns the decimal number represented
by the linked list.
4. display is a utility function which displays the contents of Linked List,
feel free to use it for debugging purposes.
5. main takes input from the users and creates the Linked List. You can use
display to know its contents.
6. This is a functional problem.
7. You should code only the func function, feel free to change its
signature if required. It should return the head of the linked list.
8. Don't change the code of Node, main and display.Input Format
First line takes N, the number of elements in the list. Next line takes input N space separated numbers 1 or 0. Input is handled for you.
Output Format
The decimal equivalent of the linked list. Output is handled for you.
Constraints
1 <= N <= 30
