Write a recursive method that has one integer parameter (n) and returns the number of binary strings of length n that do not have two consecutive I's. You should not use any loops in your solution. For example, for n = 4, the number of binary strings of length 4 that do not contain two consecutive 1's is 8: 0000,0001,0010,0100,0101,1000,1001,1010 For this problem, your method needs to return only the number of such strings, not the strings themselves. HINT: The number of such strings is the number of strings that start with a 0 plus the number of strings that start with 10.
