|
### 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"
|
||
|
|
|
||
|
|

### Expected functions
|

|
|
|

### Usage
|
||
|
|
|
||
|

Here is a program to test your function.
|
||
|
|
|
||
|
|
```rust
|
||
|
|
fn main() {
|
||
|
|
println!("{}", spell(348));
|

|
|
println!("{}", spell(9996));
|
||
|
|
}
|

|
```

|
|
And its output
|

student@ubuntu:~/[[ROOT]]/test$ cargo run
|
||
