task requires:

part of code must be in use:

must match the test:

Task 3. Complete the "quickSort(float[] a)" method so that it sorts the specified array "a" using the quicksort algorithm. For a certain time limit that you choose (e.g., 15 minutes), try to implement the method based only on your understanding of the algorithm. public static void quickSort(float [] a) \{ System.out.println(Arrays.toString(a)); for (int index = 1 ; index // TOD0: add some code here \} System.out.println(Arrays.toString(a)); public class UnitTests \{ static float[] a={5,3,1,2,4}; static float[] b={7,6,5,1,2,3,4}; @Test public void test3() throws Exception \{ float[] a1 = Arrays.copyof(a,a.length); FloatArrays.quickSort(a1); compare(a,a1); float [] b1 = Arrays.copyof(b,b.length); FloatArrays.quickSort(b1); compare(b,b1)
