Who Am I and How did I get here?

Hi, I'm a rising senior student interested in math olympiad problems especially combinatorics and puzzles in general. 

I actually have seen many strong Japanese competitors using hatena blog to share a cool problem or a trick they have encountered recently during a recent contest or past problems that they want to put spotlight on them to enlighten the readers and teach them new smart stuff! 

I hope that you will enjoy the problems that I will share in this blog!
