Selection sort is consistently O(n²) across all scenarios and is generally considered the least efficient of these three quadratic algorithms due to its non-adaptive nature.

This algorithm is generally inefficient for large lists, with a quadratic time complexity in the average and worst cases.

While O(n²) on average, it tends to perform better in practice than bubble or selection sort, especially on data that is already nearly sorted.

Merge sort is consistently efficient in all cases, making it a highly predictable and fast algorithm for large datasets.

Quick sort is very efficient on average. Its performance can degrade to O(n²) in the worst case, but
