*23.15 (Selection sort animation) Write a program that animates the selection sort algorithm. Create an array that consists of 20 distinct numbers from 1 to 20 in a random order. The array elements are displayed in a histogram, as shown in Figure 23.20a. Clicking the Step button causes the program to perform an itera- tion of the outer loop in the algorithm and repaints the histogram for the new array. Color the last bar in the sorted subarray. When the algorithm is finished, display a message to inform the user. Clicking the Reset button creates a new random array for a new start. (You can easily modify the program to animate the insertion algorithm.)
