Complete the static toStringInReverse method in the MyMethods class so that it formats an array of int values in reverse order.

The array elements should be separated by commas, and the array should be enclosed in brackets.

For example, the call toStringInReverse(new int[] { 1, 2, 3, 4 }) should return the string "[4,3,2,1]".

Complete the following file:

MyMethods.java

import java.util.ArrayList; public class MyMethods { public static String toStringInReverse(int[] values) { if (values.length == 0) return "..."; String helperResult = helper(values, ...); ... } public static String helper(int[] values, int n) { if (n == ...) return ...; String partialResult = helper(values, ...); ... } }
