int findLargestVal(int[] nums). Given an array with a length between 0 and 5, examine its elements and return the LARGEST value you find. If the array has no elements, return 0.
Use Math.max(), which takes TWO (2) parameters, e.g.

    Math.max(30,60) returns 60
    Math.max(60,30) ALSO returns 60

Below is example code for finding the largest of the first 3 elements of an array.

    int largest = Math.max(nums[0], nums[1]);
    largest = Math.max(nums[2], largest);
