Study Notes

Selection Sort Algorithm

The time complexity of Selection Sort algorithm is O(n^2) in all cases (best, average, and worst).
Selection Sort algorithm is not stable by default.
The main advantage of Selection Sort algorithm is its simplicity and ease of implementation, with minimal auxiliary memory required.

Stability of Sorting Algorithms

A stable sorting algorithm maintains the relative order of equal sort elements, whereas an unstable sorting algorithm does not.
In a stable sorting algorithm, when multiple records have the same key, their original order is preserved.
In an unstable sorting algorithm, the original order of equal keys is not preserved.

Selection Sort in Specific Scenarios

Selection sort is a good choice when the array is small, as it has low overhead in terms of auxiliary memory and is simple to implement.
However, the main disadvantage of selection sort is its inefficiency on large datasets due to its high time complexity.

Note: The notes focus on key facts and concepts related to Selection Sort, stability of sorting algorithms, and specific scenarios where it can be used effectively.
