Challenges

My attempts at completing some challenges from:

• CodeChef
• HackerRank
• /r/DailyProgrammer
• HackerEarth
• Codewars

Tech

• CodeChef solutions are developed using Python (v3.5.3). Solutions before July 2017 were developed using Python (v3.4.6).
• HackerRank solutions are developed using Python (v3.5.2).
• /r/DailyProgrammer solutions are written in Haskell (v8).
• HackerEarth SQL solutions are SQL files containing PostgreSQL (v9.5) queries.
• Codewars/Rust solutions are developed using Rust v1.43.1.

The individual directories each contain a README with more details surrounding the usage of said software.

Notes

• The code may have been cleaned up following submission to challenges, particularly around modifications to tests and command line interactions (i.e. flags/options).

  There'd be no intentional difference in logic when this happens.
