Trying to do some Leetcode, a few complaints: 1. So many meaningless variant names? u,v,s,g... . 2. Quite a few poor interfaces, for an array of 2-d points, quite a few questions use vector<vector<int>>... 3. raw new/delete flying in the code.

I can kinda understand why ACM/ICPC is this style because the focus is speed... But for an interview prep site primarily targeting software engineers - Really?

Cats on

Hi, Welcome to Cats, a private instance of the federated social network Mastodon. The name comes from the personality of cats - social, yet somewhat independent, without a single monopoly, which is a good analogy of ideal social network in my eyes.
