It sorts an array by repeatedly selecting the smallest (or largest) element from the unsorted portion and swapping it with the first unsorted element. This process continues until the entire array is sorted.First we find the smallest element an 8 min read Recursive Selection Sort The Selection Sort algorithm sorts maintain two parts. The first part that is already sortedThe second part is yet to be sorted. The algorithm works by repeatedly finding the minimum element (considering ascending order) from the unsorted part and putting it at the end of the sorted part. arr[] = 64 6 min read Time and Space complexity analysis of Selection Sort The Selection sort algorithm has a time complexity of O(n^2) and a space complexity of O(1) since it does not require any additional memory space apart from a temporary variable used for swapping. Time Complexity Analysis of Selection Sort:Best-case: O(n2), best case occurs when the array is already 2 min read Selection sort in different languagesJava Program for Selection SortThe selection sort algorithm sorts an array by repeatedly finding the minimum element (considering ascending order) from the unsorted part and putting it at the beginning.Algorithm for Selection SortImplementation of Selection Sort in Java is mentioned below:Step 1: Array arr with N sizeStep 2: Init 2 min read C Program for Selection SortThe selection sort is a simple comparison-based sorting algorithm that sorts a collection by repeatedly finding the minimum (or maximum) element and placing it in its correct position in the list. It is very simple to implement and is preferred when you have to manually implement the sorting algorit 4 min read Selection Sort - PythonSelection Sort is a comparison-based sorting algorithm. It sorts an array by repeatedly selecting the smallest (or largest) element from the unsorted portion and swapping it with the first unsorted element. This process continues until the entire array is sorted.First we find the smallest element an 2 min read Stable Selection Sort A sorting algorithm is said to be stable if two objects with equal or same keys appear in the same order in sorted output as they appear in the input array to be sorted.Any comparison based sorting algorithm which is not stable by nature can be modified to be stable by changing the key comparison op 6 min read Iterative selection sort for linked list Given a linked list, the task is to sort the linked list in non-decreasing order by using selection sort.Examples: Input : Linked List = 5 ->3 ->4 ->1 ->2Output : 1 ->2 ->3 ->4 ->5Input : Linked List = 5 ->4 ->3 ->2Output : 2 ->3 ->4 ->5Table of Content[Expe 15+ min read A sorting algorithm that slightly improves on selection sort As we know, selection sort algorithm takes the minimum on every pass on the array, and place it at its correct position.The idea is to take also the maximum on every pass and place it at its correct position. So in every pass, we keep track of both maximum and minimum and array becomes sorted from b 6 min read Program to sort an array of strings using Selection Sort Given an array of strings, sort the array using Selection Sort. Examples: Input : paper true soap floppy flower Output : floppy, flower, paper, soap, true Prerequisite : Selection Sort.

It is easy for the human brain to understand algorithms with the help of visualization. Selection sort is a simple and easy-to-understand algorithm that is used to sort elements of an array by dividing the ar 3 min read Like
