What are some optimizations for bubble sort in C++?

What are some optimizations for bubble sort in C++?

You can optimize bubble sort by implementing a flag to check if any swaps were made during a pass. If no swaps occur, the array is sorted.

How does the flag optimization work?

The flag starts as false. If a swap occurs, you set it to true. If after a full pass the flag remains false, the algorithm can terminate early.

Are there other methods to improve bubble sort performance?

Yes, you can also reduce the range of the inner loop with each pass, as the largest elements settle at the end of the array.

Is bubble sort still a good choice for sorting?

Bubble sort is generally not recommended for large datasets due to its O(n^2) complexity, but it can be useful for educational purposes.
