Playground

Backup for coding exercise files. Some of these codes arent mine, you may check at the head lines of the codes.

I also write summaries about several fundamental topics in SUMMARY.MD. I write it for interview preparations, or just have spare time and decided to learn more ehehehe.

Written in

Mostly C++, but also use Javascript (Nodejs), Golang and Python as some concepts (data structure, STL) may implemented differently in each language.

Prerequisites

Having gcc and g++ installed (c++14 better), along with build-essentials
Shell

PS: Since currently my workspace is on mac, I don't have bits/stdc++ header. It would be easier to use that header as the intention of this repo is to exercise on coding essential skills despite of its ineficiency.

Convention

Header of the file includes this following comment:

/*
 * Algorithms / Hackerrank                     # Section name
 * Queue / Mountain Climbing                   # Problem Name
 * https://hackerrank.com/problem/lorem-ipsum  # URL, if any
 * Notes: Lorem ipsum                          # Notes, if any
 */

Some of them may not include this, gonna fix it shortly
