Recursive Multiplication

Write a recursive function that accepts two arguments into the parameters x and y. The

function should return the value of x times y. Remember, multiplication can be performed

as repeated addition as follows:

7 * 4 = 4 + 4 + 4 + 4 + 4 + 4 + 4

String replacer

Write a recursive method that accepts a string as its argument and replaces the following characters.

a with e

e with i

i with o

o with u

u with a

The output should display the replaced string and total number of replacements.

For example:

Hello would be Hillu

Number of characters replaced 2
