WebAnswer: A) Q Step 2: b) The value that "V" is exchanged with is "M". After the third pass of the selection sort algorithm, the array becomes: C H J V T Q N M P W In the fourth pass (from index i = 3 to n-1), the minimum element in the unsorted part of the array is "M" at index j = 7. Since "V" is greater than "M", they are exchanged. WebBubble 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 …

This analysis can be done by hand, or found in many books. I'll use results from Knuth's Art of Computer Programming. Average number of comparisons: Bubble sort: 1 2 ( N 2 − N ln N − ( γ + ln 2 − 1) N) + O ( N) Insertion sort: 1 4 ( N 2 − N) + N − H N
WebSelection sort performs the following steps: Starting at index 0, search the entire array to find the next smallest or largest value. Swap the smallest or largest value found with the value at index 0. Repeat steps 1 & 2 starting from the next index. Question 3: Explain insertion sort.

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 smallest …
