I have taken part many times in ACM and IOI competitions and got high marks!
So, I think it easy for me! For me, Quality and accuracy is first!
But now I am web developer with 8+ year experiences.
But until now, in the rest time, I used to solve mathematical problems and algorithms.
For me, It's rest!
I know many data structures and algorithms like (tree, hash table, binary search, dynamic solution...).
And until now i have solved many problems.
So I have confidence. I look forward our meeting!
Thank u! ~_^
