in C programming your code needs to include: A structure definition for the storage of each digit's information.

A main() function to test your code.

The functions createDigit(), append(), printNumber(), freeNumber() and readNumber() which we have written in the lectures. Your task is to write a new function divisibleByThree() which takes as input a pointer that holds the address of the start of a linked list of digits. Your function should then check whether the number stored in this linked list of digits is divisible by three. The function should return the value 1 if indeed the number is divisible by three and it should return the value 0 otherwise.
