See implementation details in in MergeSort. This formulation of the algorithm is correct But it is not practical i. You are given the following 5 numbers: How many different arrangements can you make? The Selection Sort algorithm - overview Example problem: Finally, on the last step we perform n-1 comparisons to merge these two parts in one.

We will calculate the number of comparisons of an array of N elements: A note on algorithm development: Find the array element with the min. Swap this element with a[1]; Illustration: Previously, we have see: We can now refine the Selection Sort algorithm.

Next, we observe that each comparison cut down the number of all possible comparisons by a factor 2. The Selection Sort algorithm - solving subproblem 2 Problem statement: O n log n algorithms Merge-sort is based on the divide-and-conquer paradigm. In other words, the largest element has bubbled to the top of the array.

In sorting the most expensive part is a comparison of two elements. Now we are certain that the first 3 numbers are in the correct order. Insert the algorithm and we obtain a even more refined algorithm: Surely that is a dominant factor in the running time.

Here is one step of the algorithm. Consider the following array of numbers 27 10 12 25 34 16 15 31 divide it into two parts 27 10 12 25 34 16 15 31 divide each part into two parts 27 10 12 25 34 16 15 31 divide each part into two parts 27 10 12 25 34 16 15 31 10 27 12 25 16 34 15 31 merge parts 10 12 25 27 15 16 31 34 merge parts into one 10 12 15 16 25 27 31 34 How do we merge two sorted subarrays?

The largest element - 7 - is bubbled to the top: Combining these two facts, gives us the following equality: Using the Stirling formula for N!

Swap this element with a[2]; And so on until we reach the last element in the array Observation: O n2 algorithms Bubble Sort The algorithm works by comparing each item in the list with the item next to it, and swapping them if required.

At each leaf in the tree, no more comparisons to be made. Any comparison sorting algorithm can always be put in the form of a decision tree.

We still need to work out 2 smaller problems: It involves the following three steps: We visualize the mergesort dividing process as a tree Lower bound What is the lower bound the least running time in the worst-case for all sorting comparison algorithms?Write an algorithm to arrange three integer elements in ascending order.

Write an algorithm to arrange three integer elements in ascending order. Algorithm to arrange three integer elements in ascending order: Step 1: Start Step 2: Accept three numbers from user (a, b, c) Step 3: If a.

This is a C Program to sort an array in ascending order.

Problem Description This program will implement a one-dimentional array of some fixed size, filled with some random numbers, then will sort all the filled elements of the array.

Merge sort is also used in a method already mentioned by other responses mint-body.com There is no simple way how to recommend some algorithm or function call, because there are dozens of special cases, where you would use some sort, but not the other.

Here is source code of the C program to sort the numbers in ascending order using bubble sort. The C program is successfully compiled and run on a Linux system. The program output is also shown below.

Sort Three Numbers Problem Statement. Give three integers, display them in ascending order.

For example, if the input is 2, 3 and 1, this program should display 1, 2 and 3. Bubble sort program for sorting in descending Order In order to sort in descending order we just need to change the logic array[j] > array[j+1] to array[j].
