📚 About Codility

Codility problems test algorithmic thinking. Key challenges:

• Efficiency: Aim for O(1), O(n), or O(n log n)
• Edge cases: Handle empty inputs, single elements, large numbers
• Minimalist code: Avoid nested loops and unnecessary objects
• Quick exits: Use return and break to exit early

🏆 Achievements

• 32 passed test cases on latest run
• 0 failures
• 100% scores on all recent submissions
• Consistently under 6 minutes per problem
