Explain the working of selection sort
WebConquer by recursively sorting the subarrays in each of the two subproblems created by the divide step. That is, recursively sort the subarray array[p..q] and recursively sort the subarray array[q+1..r]. Combine by merging the two sorted subarrays back into the single sorted subarray array[p..r]. WebIn computer science, selection sort is an in-place comparison sorting algorithm. It has …

The first element in the array is assumed to be sorted. Take the second element and store it separately in key. Compare key with the first …
WebMajorly insertion sort and selection sort can be differentiated by the method they use to sort the data. The insertion sort inserts the values in a presorted file to sort a set of values. On the other hand, the selection … WebSelection sort is a simple sorting algorithm. This sorting algorithm is an in-place comparison-based algorithm in which the list is divided into two parts, the sorted part at the left end and the unsorted part at the …
WebThis algorithm is called selection sort because it repeatedly selects the next-smallest element and swaps it into place. You can see the algorithm for yourself below. Start by using "Step" to see each step of the algorithm, and then try "Automatic" once you understand it to … WebMar 31, 2024 · Worst Case Analysis for Bubble Sort: The worst-case condition for bubble sort occurs when elements of the array are arranged in decreasing order. In the worst case, the total number of iterations or …
WebAug 6, 2024 · 1 Answer. Sorted by: 1. This is an awful question for a test. Selection sort always has about n^2/2 comparisons and n swaps. Insertion sort has between n and n^2/2 comparisons and the same number of swaps. But as you said absolutely correctly, the actual time depends on the exact implementation. For example if you look for the …
WebBubble sort is a simple sorting algorithm. This sorting algorithm is comparison-based algorithm in which each pair of adjacent elements is compared and the elements are swapped if they are not in order. This algorithm is not suitable for large data sets as its average and worst case complexity are of Ο (n 2) where n is the number of items. black country healthcareWebThe two sorting algorithms we've seen so far, selection sort and insertion sort, have worst-case running times of Θ (n 2) \Theta(n^2) Θ (n 2) \Theta, left parenthesis, n, squared, right parenthesis.When the size of the input array is large, these algorithms can take a long time to run.
