WebMar 21, 2024 · Here are the steps to sort the given items in ascending order using Bubble Sort: Start with the first two elements, compare them, and swap if necessary. Move to the next pair of elements, compare them, and swap if necessary. Repeat step 2 for all pairs of adjacent elements until the end of the list is reached. WebFeb 19, 2015 · Running merge sort on an array of size n which is already sorted is a) O(n) b) O(nlogn) ... The lower bound on the number of comparisons performed by comparison-based sorting algorithm is a) Ω (1) b) Ω (n) c) Ω (nlogn) ... MCQs on Sorting with answers -Aarav Pant (08/14/20)
Exactly how many comparisons does merge sort make?
WebExplanation: Merge sort uses divide and conquer in order to sort a given array. This is because it divides the array into two halves and applies merge sort algorithm to each half … WebDec 4, 2024 · The number of comparisons: This is the number of times the algorithm compares elements to sort the input. Using Big-O notation, the sorting algorithm examples listed above require at least O (nlogn) comparisons in the best case, and O (n^2) comparisons in the worst case for most of the outputs. city comforts

WebMay 4, 2024 · Approach: The problem can be solved using Divide and Conquer Algorithm ( Merge Sort ). Follow the steps below to solve the problem: Split the array into two halves and recursively traverse both the halves. Sort each half and calculate the number of swaps required. Finally, print the total number of swaps required. Web62. Under what case of Master’s theorem will the recurrence relation of merge sort fall? a) 1 b) 2 c) 3 d) It cannot be solved using master’s theorem Answer: b Explanation: The recurrence relation of merge sort is given by T(n) = 2T(n/2) + O(n). So we can observe that c = Logba so it will fall under case 2 of master’s theorem. 63. WebMar 5, 2024 · The list is considered to be divided into three lists, where the left list contains the unsorted elements, the right list contains the sorted elements and the mid portion contains the key value which needs to be compared. The list is not divided, but an extra array is required to store elements. dictionary english romanian translation
