II) Objective: Add to the class called RecursiveMath that follows the given criteria and a driver class that implements the methods. a. Write a method called nthRowRecursive that returns the array of integers in the nth row of the Pascal Triangle. i. Use an array to store the values of each row. b. Write a method call nthRowCombination that outputs the integers in the nth row of the Pascal Triangle. c. Write a method called valueAt that returns the integer at the passed position of the passed row. Return 0 if no position exists. d. Write a method called nthRowSum that returns the sum of the nth row of the Pascal Triangle. e. Constructor(s), other method(s), and/or instance fields should be made at your discretion. III) Notes: a. nthRowRecursive method should be recursive. b. nthRowSun should call either of the two previous methods
