Given a non-empty array of integers, recursively compute the largest value in the array. Note: You should solve this recursively (no loops). You will need a recursive helper method that takes an array and an index as parameters. Advice: If there are at least two items to look at, then do the following: look at the first number, and let recursion tell you the max of the rest of the numbers. Return whichever is bigger. Challenge: If you use Math.max() as part of your solution, you can solve this in 2 lines of code.
