Objective: Recursive methods 1. Write a recursive method, static string reverse(String str),that reverses the input parameter string, returning the reversed string. 2. Write a recursive method, static double sumSeries (int n), to sum the following series to the nth term ( sumSeries (1) returns 1.0): 2 4 8 16 32 64 3. Write a recursive method, static int sumEvenDigits(int n), that computes the sum of the even digits in an integer. For example, sumEvenDigits (22734) returns 8 (computed from 2+2+4). 4. Provide a driver that accepts user input and tests the above three methods
