WebAug 30, 2024 · Bubble sort uses more swap times, while selection sort avoids this. When using selecting sort it swaps n times at most. but when using bubble sort, it swaps almost n* (n-1). And obviously reading time is less than writing time even in memory. The compare time and other running time can be ignored. WebDec 6, 2024 · Selection sort is a sorting algorithm that uses in-place comparison to rearrange elements in several rounds or iterations. In each round, the algorithm selects the smallest element from the given list or array and places the smallest element at the beginning of the list by swapping after comparison from every element of the list or array.
