Concept explainers

Merge sort

Merge Sort recursively sorts a given collection of numbers or elements by using the divide and conquer strategy in less time. It is one of the most used algorithms, with the worst-case time complexity of O (n log n). It was invented by John Von Neumann. The algorithm continuously divides an array into sub-arrays until each sub-array consists of a single element. It then merges those sub-arrays to produce a sorted array.

Question

Compare the sorting times of the insertion sort with QuickSort using a small array (less than 20). What is the time difference? Could you explain why?

Keep in mind that this change has no impact on the number of comparisons needed to sort an n-element list. Because that one number must be in the appropriate location, we may tweak the selection sort approach to end when only one number remains in the unsorted half of the list.
