About This Tool

**Will your code crash under load?** Writing code that works is easy. Writing code that scales is hard. The Code Complexity Analyzer is your personal algorithm auditor. It looks at your snippets and calculates the Time Complexity (Big-O) and Space Complexity instantly. It identifies nested loops, expensive recursions, and memory-hogging structures that could kill your server in production. It doesn't just judge you; it suggests specific ways to refactor your code from O(n²) to O(n) or O(log n). Essential for computer science students, LeetCode grinders, and senior engineers optimizing high-load systems.

How to use Code Complexity Analyzer?

  • Paste Code: Insert the algorithm or function.
  • Analyze: The AI calculates Big-O for time and space.
  • Review: Identify the bottleneck (e.g., the specific line causing the slowdown).
  • Optimize: Apply the suggested changes to improve performance.
