Identify performance issues and bottlenecks in code, suggesting specific optimizations.

Performance Issue Categories

1. Algorithmic Complexity

• Nested Loops: O(n²) or worse time complexity
• Inefficient Search: Linear search when hash lookup possible
• Redundant Calculations: Computing same value multiple times
• Inefficient Sorting: Using bubble sort instead of quicksort/mergesort
• String Concatenation: Building strings in loops
