Consider sorting n numbers stored in array A by first finding the smallest element of A and exchanging it with the element in A[1]. Then find the second smallest element of A, and exchange it with A[2]. Continue in this manner for the first n -1 elements of A. write pseudocode for this algorithm , which is known as selection sort. What loop invariant does this algorithm maintain? Why does it need to run for only the first n – 1 elements, rather than for all n elements? Give the best-case and worst-case running times of selection sort in Θ-notation.
This is the illustration for the execution of the insertion-sort algorithm on the input sequence (12, 11, 13, 5, 6):
