Then we are defining merge , mergeSort and printArray functions. Then we are defining the main function within which we are dividing the given array and then calling mergeSort function to sort each divided array and then calling merge function to merge the sorted arrays and then finally calling printArray function to display the resulting array as the output on the screen.

Merge sort preferred for the linked list. Sorting - This is the method used to arrange the terms or values in ascending or descending or alphabetical order or in a Data structure way. For example - you have 50 numbers and you want to arrange them in an ascending order. Searching — Search word implies to find a specific word or term in an array or group whether it is present or not. For example: - searching for a person from a group.
If Merge sort is stable and efficient but needs larger space then others then Quicksort is faster than both but it is unstable. So each algorithm is ideal for a specific set of data you need to sort. Usually, the sorting technique with O n log n complexity is fast. To choose the fastest searching algorithm depends on your need and size of the input list. If the list is not sorted then first you have to search for the element by linear search.
Although, if you are searching for multiple times, it would be better if you sort O n log n then use binary search. Quicksort is faster than merge sort because in Quicksort there is no necessity to divide the list into a half, whereas in merge sort list is always divide into half. There are three cases which an algorithm expresses in terms of at least, at most and on average resource usage, which are best, worst and average cases.
Although, complexity for all three cases is same in merge sort. Merge sort uses more space but it is stable. Don't have an account? Sign Up. Already have an account?

Noel Beck. Nigel Bright. A partition element is selected, the array is restructured such that all elements greater or less than the partition are on opposite sides of the partition.
These two parts of the array are then sorted recursively. Heap Sort. Efficient sorting algorithm which runs in O n log n time. Uses the Heap data structure. Binary Search Algorithm. Commonly used algorithm used to find the position of an element in a sorted array. Runs in O log n time. The Learning Point.
