About
I have hit the math barrier.
I am not knowledgable enough in data structures.
Why must python be so slow.
Orz CCO and IOI people.
DMs are open! Message me at AZron#8513
I want an Olympiads Boost :<

Favourite Problems
- RoboThieves - such a cool graph theory problem (orz daniel)
- Chores - really good math problem. One of the first TLE-related problems that I solved first try
- Tetris - totally not because I have an addiction on tetr.io
- CCC '20 J5/S2 Escape Room - totally worth it
- CCC '05 J5 Bananas - because I want to speak monkey
- Name That Song - you know you have no life when you spend a whole day working on a one pointer April Fools problem
- Cat Girls
- Artskjid
- A Game
- Bob's Primes - mad respect for Bob's spending habits
- Times Table - fun problem until you realize modulos are a thing (and then realize you don't actually need modulos)
- CCC '08 S2 Pennies in the Ring - fun maths
- Strict Evaluation - Segment Tree Test 2
- Tropical Bananas - OrzWilliamWu277
- CCO '17 P5 Professional Network - first 20 pointer with zero help! (orzchels)
- Palindromic Presents - could have solved in contest, but I didn't realize that 0 was a non-negative palindrome :sob:
- CCC '10 S4 Animal Farm - reading the input for this problem truly is amazing
- Permutations and Primes - my mind has been blown
Hardest Problems
- CCC '20 J5/S2 Escape Room - four attempts (starting from complete scratch) over the course of five months :/
- A Binary Problem - this should be at least a 7 pointer. Starting to realize that my math isn't good enough
- Mo' Money - not me doing unbounded knapsack instead of 0/1 knapsack, then wasting 3 hours figuring out where I went wrong
- The Final Battle - mfw you take in the input sideways, then spend an hour debugging
- CCO '12 P4 Editor Distance - when you write a solution in python that is just too slow, then convert to C++ but get a million errors because you're a noob at C++
- Bank Notes - sometimes python is just too slow
- Fast Search - why is the speed between endl and "\n" enough to TLE
- The Golden Porcupine - aka three psas and difference arrays :notlikeblob:
- String Finding - monkey string algs
- CCC '20 S3 Searching for Substrings - double hash
- Advanced Battleship - 2D sliding window with a BFS :<
- CCC '21 S3 Lunch Concert - BS on a parabola

Annoying Problems
- CCC '00 J1 Calendar - did you know calendar was spelled with an "a" and not an "e"?
- CCC '02 J1 0123456789 - This. Problem. Sucks.
- Word Search
- Do You Want to Build a Snowman - 12 point brute force
- Connect-4 - definition of cancer
Other Things
- me playing around with C++ defines Click Here
First Problems
1 pointer - Hello World
3 pointer - CCC '20 J1 Dog Treats - Actually the first problem I ever completed
5 pointer - CCC '20 J4 Cyclic Shifts - Fourth problem I ever completed
7 pointer - CCC '11 J4 Boring Business
10 pointer - CCC '01 S3 Strategic Bombing
12 pointer - CCC '13 S3 Chances of Winning - Click here for a 92 line solution with a million comments because I couldn't understand the code I was writing
15 pointer - Cat Girls
17 pointer - Stalactites - 3D BIT :blobaww:
20 pointer - Wall - funky segment tree
