/*
Some Notes:
     -The program was created in real hurry in between end term exams
     -So the program lacks all buffer overflow protections and optimization form
     -The code can be modified but please don't change the credits for the file
     -If you come up with better idea of implementing it in C, please contact me
     -If you feel program is complete crap, do comment me personally or here
     -If you loved my coding, I feel really glad for that.
     -If you need to understand the coding(in fact, its just easy), contact me..
