# Difference between Quick Sort and Merge Sort

Are you familiar with the term “sorting algorithms”? Most likely! When having to sort a large number of elements, these algorithms come into play. But what are Quick Sort and Merge Sort and how do they differ from each other? In this blog post, we will cover both sorting algorithms so that you can have a better understanding about them, know when to apply which algorithm for the best results, and compare the differences between Quick Sort and Merge Sort. Let’s dive in!

## What is Quick Sort?

• Quick Sort and Merge Sort are two very different sorting algorithms that are commonly used to sort large amounts of data. Quick Sort uses the divide-and-conquer approach, where it breaks down the data into smaller parts, allowing for quicker sorting.
• In contrast, Merge Sort follows a bio-mimicked technique; it divides the dataset in half and then merges each respective part together until all data points are in order. Quick Sort works best with small datasets, while Merge Sort works well when dealing with larger datasets as it can be easily parallelized.
• Quick Sort is typically faster than Merge Sort since Quick Sort doesn’t require merging multiple subarrays back together; however, Merge Sort is more reliable and produces results with fewer comparisons than Quick Sort. Each algorithm has its own advantages and disadvantages, so it is important to understand which one works best before implementing it in any application.

## What is Merge Sort?

Merge Sort is a sorting algorithm that is frequently used to arrange items into an ordered sequence. Merge Sort works by dividing an array of elements into two parts, and then repeatedly splits each subarray until the combined length is 1. At this point, Merge Sort merges back from the bottom up, combining sorted subsequences to produce a fully-sorted list.

Merge sort is very efficient for large sets of data because it minimizes the number of comparisons it needs to perform; sorting algorithms that can take more than a linear amount of time for large sets of data typically require additional storage space for merging. Merge sort is particularly popular in software development because it’s fast and stable, meaning it produces the same result when giving the same input every time.

## Conclusion

There are several different sorting algorithms that computer scientists use to organize data. Two of the most popular methods are Quick Sort and Merge Sort. Though both types of sorts accomplish the same goal, they go about it in different ways. Quick Sort is typically faster than Merge Sort, but Merge Sort is more reliable. When deciding which sort to use for your project, consider how important speed is versus reliability.
