If your first name starts with a letter from A-J inclusively:
Write a recursive method that takes a string as argument and determines if the string has more vowels than consonants. Test the method by asking the user to enter a string. Hint: Write your recursive method to first count vowels and consonants.

1. Write a recursive method expFive(n) to compute y=5^n. For instance, if n is 0, y is 1. If n is 3,
then y is 125. If n is 4, then y is 625. The recursive method cannot have loops. Then write a
testing program to call the recursive method. If you run your program, the results should look like
this:
> run RecExpTest
Enter a number:
3
125
>run RecExpTest
Enter a number:
3125
2. For two integers m and n, their GCD(Greatest Common Divisor) can be computed by a
recursive function. Write a recursive method gcd(m,n) to find their Greatest Common
Divisor. Once m is 0, the function returns n. Once n is 0, the function returns m. If neither
is 0, the function can recursively calculate the Greatest Common Divisor with two
smaller parameters: One is n, the second one is m mod n. Although there are other
approaches to calculate Greatest Common Divisor, please follow the instructions in
this question, otherwise you will not get the credit. Meaning your code needs to follow
the given algorithm.

Let product(n,m) be a recursive method that computes the product of two positive integers, using only addition and subtraction.
