Hacker Rank Solutions

My solutions to Hacker Rank topics, covering:

• Python (great for practising the standard library and built-ins)
• SQL (MS-SQL: great for learning or revising the essentials)
• Problem Solving (Python: work-in-progress)
• Functional Programming (Scala: work-in-progress)
• ...

Development Environment

Designed to work on MacOS / Linux / WSL

Python

Standard Python3 should suffice for most problems and won't require additional setup.

For the numpy challenges and harder problem-solving challenges (where more-itertools and other third-party libraries may be used) the makefile can be used in a terminal:

• make build (only required the first time) will create a Python virtual environment and install our additional dependencies
• make run can be used to activate our virtual environment (alt. source venv/bin/activate)
• make clean will remove the venv folder

SQL

All SQL solutions are targetted at MS-SQL, as sadly PostgreSQL is not an option.
