id=\"What_is_a_Selection_Sort_Algorithm\"><\/span><strong>What is a Selection Sort Algorithm?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Selection sort is a simple sorting algorithm that works by repeatedly finding the smallest element from the unsorted part of the list and swapping it with the first unsorted element. <\/p>\n\n\n\n<p>It starts at the beginning of the list and scans through the entire list to find the smallest value and then swaps it with the element in the first position. Then it moves to the next position and repeats the process for the remaining unsorted elements. This continues until all the elements are sorted in order. <\/p>\n\n\n\n<p>Although it is easy to understand and implement selection sort which is not very efficient for large lists because it requires repeatedly scanning through the remaining elements which is making it slower compared to more advanced sorting methods.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-how-selection-sort-algorithm-works\"><span class=\"ez-toc-section\" id=\"How_Selection_Sort_Algorithm_Works\"><\/span><strong>How Selection Sort Algorithm Works?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Selection Sort works by dividing the list into two parts which is the sorted part and the unsorted part. The sorted part is empty, and the unsorted part is the entire list.<\/p>\n\n\n\n<p>The algorithm repeatedly finds the smallest element from the unsorted part and swaps it with the first unsorted element which is adding it to the sorted part. This process continues until the entire list is sorted.<\/p>\n\n\n\n<p>Let us say we have a list:<br>[29, 10, 14, 37, 13]<\/p>\n\n\n\n<ol>\n<li>Find the smallest element \u2192 10<br>Swap it with the first element \u2192 [10, 29, 14, 37, 13]<\/li>\n\n\n\n<li>Find the smallest in remaining list \u2192 13<br>Swap with second element \u2192 [10, 13, 14, 37, 29]<\/li>\n\n\n\n<li>Find smallest in remaining \u2192 14<br>Already in place \u2192 [10, 13, 14, 37, 29]<\/li>\n\n\n\n<li>Find smallest in remaining \u2192 29<br>Swap with 37 \u2192 [10, 13, 14, 29, 37]<\/li>\n<\/ol>\n\n\n\n<p>Now the given list of array is sorted.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><a href=\"https:\/\/chat.whatsapp.com\/B6weknl7133BQXjPva0pgB\"><img decoding=\"async\" width=\"875\" height=\"142\" src=\"https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2025\/05\/image-64.png\" alt=\"\" class=\"wp-image-49174\" srcset=\"https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2025\/05\/image-64.png 875w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2025\/05\/image-64-300x49.png 300w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2025\/05\/image-64-768x125.png 768w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2025\/05\/image-64-150x24.png 150w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2025\/05\/image-64-696x113.png 696w\" sizes=\"(max-width: 875px) 100vw, 875px\" \/><\/a><\/figure><\/div>\n\n\n<h2 class=\"wp-block-heading\" id=\"h-implementation-of-selection-sort-algorithm\"><span class=\"ez-toc-section\" id=\"Implementation_of_Selection_Sort_Algorithm\"><\/span><strong>Implementation of Selection Sort Algorithm<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The implementation of selection sort algorithm is explained below in that we have taken array [15, 8, 2, 20, 11, 4] and the easy implementation of code in python programming language.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" width=\"596\" height=\"717\" src=\"https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2025\/05\/image-61.png\" alt=\"\" class=\"wp-image-49161\" style=\"width:325px;height:auto\" srcset=\"https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2025\/05\/image-61.png 596w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2025\/05\/image-61-249x300.png 249w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2025\/05\/image-61-349x420.png 349w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2025\/05\/image-61-150x180.png 150w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2025\/05\/image-61-300x361.png 300w\" sizes=\"(max-width: 596px) 100vw, 596px\" \/><\/figure><\/div>\n\n\n<pre class=\"wp-block-code\"><code>arr = &#091;15, 8, 2, 20, 11, 4]\r\nn = len(arr)\r\n\r\n# Selection Sort\r\nfor i in range(n):\r\n    min_idx = i\r\n\r\n    for j in range(i + 1, n):\r\n        if arr&#091;j] &lt; arr&#091;min_idx]:\r\n            min_idx = j\r\n\r\n    # Swap\r\n    arr&#091;i], arr&#091;min_idx] = arr&#091;min_idx], arr&#091;i]\r\n\r\nprint(\"Sorted array:\", arr)\r\n<\/code><\/pre>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-complexity-analysis-of-selection-sort-algorithm\"><span class=\"ez-toc-section\" id=\"Complexity_Analysis_of_Selection_Sort_Algorithm\"><\/span><strong>Complexity Analysis of Selection Sort Algorithm<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>This table shows the complexity analysis of selection sort algorithms in every possible way whether it is best case, average case and worst case.
