must provide the following public interface: public static void insertSort(int [] arr); public static void selectSort(int [] arr); public static void quickSort(int [] arr); public static void mergeSort(int [] arr); The quick sort and merge sort must be implemented by using recursive thinking. So the students may provide the following private static methods: //merge method //merge two sorted portions of given array arr, namely, from start to middle //and from middle + 1 to end into one sorted portion, namely,...
