algostem
"AlgoSTEM is an organization created by co-founders Arushi and Akshaj Gupta. Both co-founders have past experience in competitive programming and math and understand the fundamentals behind advanced algorithms and data structures.
Our mission is to provide free educational resources to anyone interested in learning computer science, math, and physics at a higher level.
We regularly publish videos on our Youtube channel, Algorythm, and create courses on Udemy. We cover problems from popular programming contests and interview sites such as Leetcode, Codeforces, Codechef, AtCoder, and more in our videos. We have also started Math sections focused on AMC 8/10/12 and AIME as well as other competitions."
