Use of std::vector:

Replaced the raw array with std::vector, which allows for dynamic sizing and better memory management.
Tracking Last Swap Position:

Introduced a variable lastSwapIndex to track the last position where a swap occurred. This helps to reduce the number of comparisons in subsequent passes, as any elements after this index are already sorted.
Const-Correctness:

Changed the display function to take a const vector& instead of a raw pointer. This emphasizes that the function does not modify the input vector.
Minor Code Cleanups:

Streamlined the swapping function by initializing temp directly.
Used a range-based for loop in the display function for improved readability.
These changes collectively improve both performance and clarity while maintaining the core functionality of the Bubble Sort algorithm.
