Challenge 16: Performance Optimization with Benchmarking

In this challenge, you will optimize several Go functions for performance, using benchmarking to measure your improvements. You'll work with a set of common but inefficient implementations and apply various techniques to make them faster without changing their functionality.

Requirements

1. Optimize the following functions while preserving their behavior:

   • SlowSort: An inefficient sorting implementation
   • InefficientStringBuilder: A function that builds large strings inefficiently
   • ExpensiveCalculation: A CPU-intensive calculation with unnecessary work
   • HighAllocationSearch: A search function that allocates excessively

2. For each optimization:

   • Use Go's benchmarking tools to measure performance before and after
   • Document the approach you took and the improvement achieved
   • Ensure the function still passes all tests

3. Apply techniques such as:

   • Reducing memory allocations
   • Using more efficient algorithms
   • Taking advantage of Go's standard library
   • Removing redundant calculations
   • Using appropriate data structures

4. Run benchmarks with different input sizes to analyze algorithmic complexity

5. The included test file verifies both correctness and performance improvement
