README

This is my repository for personal leetcode solutions. Most code should be written in Javascript, but other language might be used as well.

Abbreviation Naming

When trying to use multiple solutions towards one problem, the following abbrevations might be used as postfix.

Abbreviation	Name
BS	Binary Search
BT	Backtracking
BFS	Breadth-first Search
DC	Divide and Conquer
DFS	Depth-first Search
DP	Dynamic Programming
GD	Greedy
HM	Hashmap

Note

To view unsolved problems locally, run sh ./list-unsolved.sh, or install this tampermonkey script if you prefer to view from website.
