Question:
Write a program which accepts a sequence of comma separated 4 digit binary 
numbers as its input and then check whether they are divisible by 5 or not. 
The numbers that are divisible by 5 are to be printed in a comma separated sequence.
Example:
0100,0011,1010,1001
Then the output should be:
1010
Notes: Assume the data is input by console.
