Write a method named firstDigit that returns the first digit of an integer. For example, `firstDigit(3572)` should return `3`. It should work for negative numbers as well. For example, `firstDigit(-947)` should return `9`.

Call Value Returned
`firstDigit(3572)` `3`
`firstDigit(-947)` `9`
`firstDigit(6)` `6`
`firstDigit(35)` `3`
`firstDigit(123456)` `1`

(Hint: Use a `while` loop. You may not use a `String` to solve this problem.)
