Instructions

In this exercise a number between 0 and 1000000 will be generated. Your purpose is to create the function spell that will spell the numbers generated.

So, if the program generates the number:

  • 1 your function will return the string "one"
  • 14 your function will return the string "fourteen".
  • 96 your function will return the string "ninety-six"
  • 100 your function will return the string "one hundred".
  • 101 your function will return the string "one hundred one"
  • 348 your function will return the string "one hundred twenty-three"
  • 1002 your function will return the string "one thousand two".
  • 1000000 your function will return the string "one million"

Only positive numbers will be tested. (Up to a million).

Notions

Expected function

pub fn spell(n: u64) -> String {

}

fn main() {
    println!("{}", spell(348));
    println!("{}", spell(9996));
}
