Design and analysis of algorithms merge sort

How do you create a merge sort algorithm?
So, the merge sort working rule involves the following steps:
1. Divide the unsorted array into subarray, each containing a single element
2. Take adjacent pairs of two single-element array and merge them to form an array of 2 elements
3. Repeat the process till a single sorted array is obtained

What is quick sort in design and analysis of algorithms?
Quicksort is a divide-and-conquer algorithm.
It works by selecting a 'pivot' element from the array and partitioning the other elements into two sub-arrays, according to whether they are less than or greater than the pivot..
Which algorithm design technique is used in merge sort algorithm?
Merge Sort is a Divide and Conquer algorithm.
It divides the input array into two halves, calls itself for the two halves, and then merges the two sorted halves.
Both Merge Sort and quicksort are based on the divide and conquer method..
Divide and conquer algorithms (which merge sort is a type of) employ recursion within its approach to solve specific problems.
Divide and conquer algorithms decompose complex problems into smaller sub-parts, where a defined solution is applied recursively to each sub-part.
Sorting is the process of arranging the elements of an array so that they can be placed either in ascending or descending order.
For example, consider an array A = {A1, A2, A3, A4, ?? An }, the array is called to be in ascending order if element of A are arranged like A1 \x26gt; A2 \x26gt; A3 \x26gt; A4 \x26gt; A5 \x26gt; ? \x26gt;

Then, merge sort combines the smaller sorted lists keeping the new list sorted too.

Step 1 − if it is only one element in the list, consider it already sorted, so return.
Step 2 − divide the list recursively into two halves until it can no more be divided.
Step 3 − merge the smaller lists into new list in sorted order.

Merge sort is a sorting technique based on divide and conquer technique. With worst-case time complexity being Ο(n log n), it is one of the most used and approached algorithms. Merge sort first divides the array into equal halves and then combines them in a sorted manner.

Divide and Conquer Idea of Merge Sort

Suppose we need to sort an array A[lr] of n integers starting from index l and ending at index r

Divide and Conquer Steps of Merge Sort

Suppose the function mergeSortAlgorithm(int A[], int l, int r)sorts the entire array A[] with left and right ends as input parameters. 1

Implementation of Merging Algorithm

Solution idea: Two pointers approach After the conquer step, both left part A[l…mid] and right part A[mid + 1…r]will be sorted

Merge Sort Algorithm Time Complexity Analysis

Let's assume that T(n) is the worst-case time complexity of merge sort for n integers. We can break down the time complexities as follows: 1

Space Complexity Analysis of Merge Sort Algorithm

The space complexity of the merge sort algorithm depends on the extra space used by the merging process and the size of the recursion call stack used

Iterative Merge Sort Algorithm

We can implement merge sort iteratively without using an explicit auxiliary stack. On another side

What are the disadvantages of merge sort?

Another disadvantage of merge sort is that it will execute the operational steps even if the initial list is already sorted

In the use case of sorting linked lists, merge sort is one of the fastest sorting algorithms to use

Merge sort can be used in file sorting within external storage systems, such as hard drives

What is a merge sort algorithm?

As noted earlier in this article, the merge sort algorithm is a three-step process: divide, conquer, and combine

The ‘divide’ step involves the computation of the midpoint of the list, which, regardless of the list size, takes a single operational step

Therefore the notation for this operation is denoted as O (1)
