Selection Sort Algorithm In Programming. Selection sort algorithm starts by compairing first two elements of an array and swapping if necessary, i. Then, again first element and third element are compared and swapped if necessary. This process goes on until first and last element of an array is compared. This completes the first step of selection sort.
This tutorial explains how the selection sort algorithm works and shows you how to implement the selection sort in C. The following is the output of the selection sort program. C goto; C Array; C String; C. Array is imaginary divided into two parts. Selection sort stops, when unsorted part becomes empty. SELECTION SORT Write a C program to perform selection sort on an array of n elements. Input Format: Input consists of n+1 integers. The first integer corresponds to n, the number of elements in the array. Selection sort and insertion sort are two simple sorting algorithms. What this means in practice is that the sort iterates down an array. 5 ways you can learn to program faster. If there are n elements to be sorted then, the process mentioned above should be repeated n- 1 times to get required result. But, for better performance, in second step, comparison starts from second element because after first step, the required number is automatically placed at the first (i. In case of sorting in ascending order, smallest element will be at first and in case of sorting in descending order, largest element will be at first.). Similarly, in third step, comparison starts from third element and so on. A figure is worth 1. This figure below clearly explains the working of selection sort algorithm.#include < stdio. Enter element: 0. In ascending order: 0 1 2 1. Note: Though this program is in C, selection sort algorithm can be similarly used in other programming language as well. Selection sort algorithm is easy to use but, there are other sorting algorithm which perform better than selection sort. Specially, selection sort shouldn't be used to sort large number of elements if the performance matters in that program.
