The process of placing or rearranging a collection of elements into a particular order is known as sorting. Bubble sort is the simplest sorting algorithm that works by repeatedly swapping the adjacent elements in case they are unordered in n-1 passes. In Selection Sort, the smallest element is selected from the unsorted array and swapped
