### 250+ TOP MCQs On Merge Sort And Answers

Clarification: Merge sort algorithm divides the array into two halves and applies merge sort algorithm to each half individually after which the two sorted halves are merged together. Thus its method of sorting is called merging. 7. What will be the best case time complexity of merge sort? a) O(n log n) b) O(n 2) c) O(n 2 log n) d) O(n log n 2 ...

### Quicksort - Wikipedia

Quicksort is an in-place sorting algorithm.Developed by British computer scientist Tony Hoare in 1959 and published in 1961, it is still a commonly used algorithm for sorting. When implemented well, it can be somewhat faster than merge sort and about two or three times faster than heapsort. [contradictory]Quicksort is a divide-and-conquer algorithm.It works by selecting a …

### Merge - C++ Reference

Complexity Up to linear in (1+count1-count2), where countX is the distance between firstX and lastX: Compares and assigns all elements. Data races The objects in the ranges [first1,last1) and [first2,last2)are accessed. The objects in the range between result and the returned value are modified. Exceptions Throws if any of element comparisons, the element assignments or the …

### Insertion Sort - GeeksforGeeks

Jul 08, 2021 · Insertion sort is a simple sorting algorithm that works similar to the way you sort playing cards in your hands. The array is virtually split into a sorted and an unsorted part. Values from the unsorted part are picked and placed at the correct position in the sorted part. Algorithm To sort an array of size n in ascending order:
