ABOUT
I started Competitive Programming in 2019, and eventually reached a peak rating of 2353 (International Master) on Codeforces.
In Fall 2022, I started a Competitve Programming club at Berkeley, and my team placed third at ICPC Regionals in both 2022 and 2023.
PROBLEMS I'VE AUTHORED
As president of my high school computer science club, I created over 150 original problems for implementation-based practice contests, as well as 24 competitive programming problems for contests that were open to participants worldwide.
Here are some of the highlights:
MAXIMUM DONUT Difficulty: Hard
Use prefix sum arrays and a clever formula to find the largest "donut" shape in a 2D grid
INFECTIOUS LETTERS Difficulty: Easy
Find which characters in a string are "infected" using some observations
BIRDWATCHING Difficulty: Medium
Use an ordered map to find the best way to place cameras to take pictures of birds
NUMBER PLACEMENT Difficulty: Medium
Use Depth-First Search and the Sieve of Eratosthenes to place prime numbers in a grid
MAXIMUM PLUS SIGN Difficulty: Medium
Similar to maximum donut, use prefix sums to find the maximum plus sign in a grid
PLANE AND SIMPLE Difficulty: Hard
Use Knapsack Dynamic Programming to optimally place luggage on a conveyor belt
