5/24/2023 0 Comments Selection sort vs bubble sortOptimized Bubble Sort: If, in a pass, we do not make any swaps, then we don’t need to make any further passes. ![]() The array is sorted when all the unsorted elements are placed at their respective correct positions. ![]() In each pass, the comparison takes place up to the last unsorted element. After each pass, the largest element among the unsorted elements is placed at the end. The same process goes on for the remaining passes.The first pass is complete - largest element present will be at the end of the array. This process goes on until the last element. ![]() If the first element is greater than the second element, swap them else, leave them as it is. Starting from the first index, compare the first two elements.Bubble Sort Algorithm (in ascending order) It keeps on making the passes until the whole array is sorted. Key Differences between Bubble Sort and Selection Sortīubble sort is a comparison-based sorting algorithm that involves making passes over the input array where, in each pass, adjacent elements are swapped if they are not present in the required order (ascending or descending).We have a table of differences further in this article. ![]() But before going through the key differences between them, let's understand how both of these algorithms work. Bubble sort and Selection sort are both comparison-based sorting algorithms which can be differentiated through the methods they use for sorting.
