Ruby DSA Practice

Post–Le Wagon Ruby fundamentals & data structures/algorithms practice. Each problem lives in its own folder under problems/, with a spec so I can verify my solution before pushing.

Structure

problems/
  001-example/
    problem.md       # the problem statement
    solution.rb       # my solution
    spec/
      solution_spec.rb # tests for the solution

Workflow

1. Get a new problem, scaffolded via bin/new_problem <slug>.
2. Read problem.md, write my solution in solution.rb.
3. Run the spec: bundle exec rspec problems/<folder>/spec
4. Once green, commit and push.

Setup

bundle install

Running all specs

bundle exec rspec
