Merge sort bubble sort

Bubble sort Bubble sort is considered the simplest sorting algorithm. It goes through an entire array and compares each neighboring number. It then swaps.

If you are going to implement a function which takes an integer array as input and returns the maximum, would you use bubble sort or merge sort to implement this function? What if the array size is less than ? What if it is greater than ? First, it is really weird to use sorting to implement the above function. You can just go through the array once and find the max one.

Sorting data means arranging it in a certain order, often in an array-like data structure. You can use various ordering criteria, common ones being sorting numbers from least to greatest or vice-versa, or sorting strings lexicographically. You can even define your own criteria, and we'll go into practical ways of doing that by the end of this article. If you're interested in how sorting works, we'll cover various algorithms, from inefficient but intuitive solutions, to efficient algorithms which are actually implemented in Java and other languages. There are various sorting algorithms, and they're not all equally efficient. We'll be analyzing their time complexity in order to compare them and see which ones perform the best.

Bubble sort , sometimes referred to as sinking sort , is a simple sorting algorithm that repeatedly steps through the list, compares adjacent elements and swaps them if they are in the wrong order. The pass through the list is repeated until the list is sorted. The algorithm, which is a comparison sort , is named for the way smaller or larger elements "bubble" to the top of the list. Although the algorithm is simple, it is too slow and impractical for most problems even when compared to insertion sort. Therefore, bubble sort is not a practical sorting algorithm.

Merge Sort

Bubble Sort is the simplest sorting algorithm that works by repeatedly swapping the adjacent elements if they are in wrong order. The algorithm needs one whole pass without any swap to know it is sorted. Following is the implementations of Bubble Sort. Worst case occurs when array is reverse sorted. Best Case Time Complexity: O n.

It divides input array in two halves, calls itself for the two halves and then merges the two sorted halves. The merge function is used for merging two halves. The merge arr, l, m, r is key process that assumes that arr[l.. See following C implementation for details. If we take a closer look at the diagram, we can see that the array is recursively divided in two halves till the size becomes 1.
