I am retired from competitive programming, but my Python and C++ history can be found here. I can do greedy algorithms, dynamic programming, recursion, backtracking, and graph theory problems.

March 8 2022: When did they change the DMOJ ratings to drop me from purple to blue?!

I was born on July 18th 2002, Im in Grade 10 (11 now) (01/05/20 a.k.a January 5th 2020: 12 now! May 2nd 2021: I will stop updating this) and I do math contests. I hope to solve the Riemann Hypothesis someday. Im in Earl Haig S.S (6/30/20 got accepted to UWaterloo CS'25 or the infamous 225% class) and I can't do 7 point problems T_T

CCC 2018 (Junior): 57/75 (Forgot to typecast to an int mfw)

CCC 2019 (Senior): 36/75 (Could've gotten 39 if I went for partials but only score that matters to me is CCO or no CCO. Originally reported 34 but my last submission took a while to be judged and gave me 36.)

CCC 2020 (Senior): 33/75 (15/15/3/0/0. Legitimately very bad, but at least Andrew Xue got 69 and will represent my school at CCO!)
