![]() ![]() (Where n is a number of elements in the array (array size).). If you look at steps 2, 3, 4 and 5 iterates ‘n’ number of times. The time complexity of the Selection Sort algorithm: If you want to sort the array in descending order, (step 2 in the algorithm) find the largest element rather than the smallest element. This program and algorithm sort the array in ascending order. The output of a Program: Given Array: 5 35 5 31 56 You can take the array elements as user input as well. Note: We have assigned elements to the array in the program itself. However, it uses very small amount of memory to replace the elements. It takes a constant amount of space and does not require any auxiliary data structure for sorting. Selection sort is the in-place sorting algorithm. Selection sort is the in-place sorting algorithm, Why? Repeat step 2, 3 and 4 until ‘i’ reaches to the last element in an array.Increment ‘i’ to point it to next element in the array.Replace the smallest element with the array element placed at position ‘i’.Select the smallest element from the array.Keep a pointer to the first element of the array (says i).Stepwise Explanation for Selection Sort Algorithm: Selection sort is an algorithm where we keep finding the smallest element and then we order them in sequence. In this C programming tutorial, we see the program for selection sort in C with explanation in detail. ![]() Some of the simple and widely used algorithms are as follows. There are many sorting algorithms to sort the elements in the array. ![]()
