I’ve published a collection of Interactive Coding Challenges on GitHub.

 

interactive-coding-challenges

Continually updated, interactive and test-driven coding challenges.

Challenges focus on algorithms and data structures that are typically found in coding interviews orcoding competitions.

Each challenge has one or more reference solutions that are:

  • Fully functional
  • Unit tested
  • Easy-to-understand

Challenges will soon provide on-demand incremental hints to help you arrive at the optimal solution.

Notebooks also detail:

  • Constraints
  • Test cases
  • Algorithms
  • Big-O time and space complexities
