A test harness program for testing sorting methods is provided with the rest of the textbook program files. It is the file Sorts.java in the ch11 package. The program includes a swap method that is used by all the sorting methods to swap array elements.

Describe an approach to modifying the program so that after calling a sorting method the program prints out the number of swaps needed by the sorting method.

Implement your approach.

Test your new program by running the selectionSort method. Your program should report 49 swaps.
