In this program user would be asked to enter the number of elements along with the element values and then the program would sort them in ascending order by using bubble sorting algorithm logic. Bubble sort compares all the element one by one and sort them based on their values.
The bubble sort requires very little memory other than that which the array or list itself occupies. The bubble sort is generally considered to be the simplest sorting algorithm. Pdf sorting a list of items is one basic task in many applications used on the computer. For example, in bubble sort and merge sort, there is an option to also compute the inversion index of the input array this is an advanced topic. Even other n 2 sorting algorithms, such as insertion sort, generally run faster than bubble sort, and are no more complex. Both worst case and average case complexity is o n 2. Some sorting algorithms have certain additional options. In example, here is when the array is 800,11,50,771,649,770,240, 9. The elements must have a total order and the index of the array can be of any discrete type. There are many fast sorting algorithms like quicksort, heapsort.
