USA Computing Olympiad
Most commonly pronounced as: You-Suck-Oh (or less commonly; You-Sack-Oh)

A 4-hour long, online programming competition for highschool kids where there are four divisions: Bronze, Silver, Gold, and Platinum. Each division features different types of problems, such as sorting, binary search, DP, greedy, graph theory, blah blah, etc.

Helpful Side-note:
Once you reach the 4th division (Platinum), you will realize that the pronounciation of the name makes sense.
Gaddamit, I forgot ONE edge-case for my program, and that killed 8 test cases!! Gaddammit, I missed the USACO Platinum cuttoff by ONE test-case..... Gaddammit, my code won't even compile!!

....I realized that I was a USACO(You-Suck-Oh).
