Selection Sort

Selection Sort:

Selection Sort is a simple sorting algorithm that divides the input list into a sorted and an unsorted region. The algorithm repeatedly selects the smallest (or largest) element from the unsorted region and swaps it with the first element of the unsorted region. Let's explore the key concepts and properties of Selection Sort:

Algorithm Overview:

The basic idea behind Selection Sort is to iteratively find the minimum (or maximum) element from the unsorted region and swap it with the first element of the unsorted region. This process continues until the entire list is sorted.

Basic Steps:

• Selection: Find the minimum (or maximum) element in the unsorted region.
• Swap: Swap the found element with the first element of the unsorted region.
• Move Boundaries: Move the boundaries between the sorted and unsorted regions.

Time Complexity:

Selection Sort has a time complexity of O(n^2), similar to Bubble Sort. While it is also inefficient for large lists, it performs better than Bubble Sort in terms of the number of swaps.

Use Cases:

• Simplicity: Selection Sort is easy to understand and implement, making it suitable for educational purposes.
• Small Lists: In cases where the list size is small and simplicity is prioritized over efficiency, Selection Sort can be used.
• Minimizing Swaps: If the cost of swapping elements is a concern, Selection Sort may be preferred over Bubble Sort.
