You will produce a short, elegant, recursive algorithm that spells out any number between 1 and 2.1 billion. Allow the user to input a number in the range from 1 to 2.1 billion (a positive 32-bit int), then spell out the number (e.g. 123456 would output "one hundred twenty three thousand four hundred fifty six"). Chap12 updated2say has a simple flow diagram that could represent the logic you use for this. Use a recursive method "say(n)" where n) returns the string corresponding to the input integer n. The beauty of recursion is that this can be done with just a few if statements and switch case values (about 30 or so tot thanks to the way we read numbers (the number 123, 123, 123 is spoken the same as a single 123. but with a few "place" words million, thousand, etc.).
