## Imported questions (45)

file `03-javascript/output-based-questions.md`.

## Original questions (130)

All other questions are original to this project. Several use classic, widely published problem
names (Two Sum, FizzBuzz, binary search, balanced brackets) with newly written statements, solutions and tests.
