leetcode

A JavaScript repository that tracks one developer's LeetCode work and pairs it with a 91 day algorithm practice group built around daily check ins.

The GitHub description calls it a record of a problem solving journey. The README goes further and attaches a study apparatus to the solutions: a membership discount page for LeetCode, a 91 day algorithm activity, and an offer of one on one tutoring. The author's stated belief is that learning algorithms depends on accumulation, that quantity has to come before quality.

The 91 day activity is an organized practice group with a set learning path and enforced daily check ins. The README is fairly critical of the seven day or one month interview prep courses floating around, arguing that steady accumulation works better. The author also accepts 1v1 algorithm tutoring, priced according to the student's current foundation and the content wanted.

Beyond the solutions, the README explains a daily question activity run inside WeChat and QQ groups, where everyone solves one problem together and the results get filtered into the solutions module later. A guide to basic techniques lists divide and conquer, binary search, greedy, sorting, search, graph theory, and dynamic programming topics like knapsack and longest subsequence. A medium difficulty collection carries the advice to code each solution yourself even after reading the explanation, because the details only stick through writing them. A third party plugin site estimates contest scores based on pass counts, and the homepage links to a Gitbook version.

The repository is really two things at once: a public record of solved problems and a hook for a study community. For a learner the more interesting part is the method: daily practice and writing every solution by hand, rather than the answers themselves.
