Quicksort is an optimized sorting algorithm. It makes use of divide and conquer logic to sort the series. Let us understand: How Quicksort works (Easy Explanation) : The array obtained at the end will be sorted. Take a look at below image to get more clarity on steps:- Let us take take a look at … Read more
In selection sorting each element is compared with all the following elements of the array. If the element is greater than any following element then swapping is done. After the first cycle we obtain the smallest element at the starting. Now in the second cycle, second element is compared with all following elements to obtain … Read more
