Combinatorics in Competitive Programming

Since the beginning of my preparation for competitive programming I have seen number of problems based on most important topic of mathematics, that is, combinatorics. Can someone point out a good source for the same. Thank you.


This Topcoder tutorial would be great place to start combinatorics


Mott, Kandel, Baker, Discrete Mathematics for Computer Scientists and Mathematicians,2nd Edition,

it is one of the good books you can refer for combinatorics…
