Optimizations and Comments: Parameter Passing: Changed from passing vectors by value to by constant reference to avoid unnecessary copies. Initialization: Used direct initialization of ans vectors with default values (n for next smaller, -1 for previous smaller), simplifying the logic. Stack Condition: Added !s.empty() checks to ensure safe stack operations. Code Simplification: Removed redundant variable assignments and clarified the width and area calculations. INT_MIN Replacement: Replaced INT_MIN with 0 for initializing maxArea since area can't be negative.
