In this tutorial, we will learn about c program to sort array using bubble sort algorithm.
Greedy algorithms this is not an algorithm, it is a technique. Bubble sort is a simple sorting algorithm that works by repeatedly stepping through the list to be sorted, comparing each pair of adjacent items and swapping them if they are in the wrong order. Like bubble sort, the insertion sort algorithm is straightforward to implement and understand. To apply the bubble sort we follow the following steps. The selection sort algorithm is based on the idea of finding the minimum or maximum element in an unsorted array and then putting it in its correct position in a sorted array.

For example, the lower part of an array is maintained to be. Further, the algorithm does linear search to nd ith minimum. This sorting algorithm is comparisonbased algorithm in which each pair of adjacent elements is compared and the elements are swapped if they are not in order. Insertion sort algorithm sorts array by shifting elements one by one and inserting the right element at the right position. This can be tracked by the bubble sort algorithm through a so called swap flag. The bubble sort algorithm isnt efficient as its averagecase complexity is on 2 and worstcase complexity is on 2.
We can create a java program to sort array elements using bubble sort. Merge sort is a divideandconquer algorithm based on the idea of breaking down a list into several sublists until each sublist consists of a single element and merging those sublists in a manner that results into a sorted list.
