This is one of my everlasting side projects. I solve CS puzzles to master my algorithmic skills and to reflect about perfect solution for various CS problems. For the last 10 years I have solved in total 2000+ problems. This repository contains about 500 of them, mostly of mid-level complexity
The package problem contains solutions of some medium-level complexity problems. The main accent is made on optimization and simplicity of solution. All problems are grouped by category (total 39 categories):
array
backtracking
bfs
binarysearch
bitmanipulation
bst
buckets
combinatorics
design
dfs
dividenconquer
dp
game
graph
greedy
hashtable
heap
intervals
linesweep
linkedlist
math
