# Problem: Numbers to Words

Write a method Letterize(number), which reads an integer and prints it in words in English according to the conditions below:

• Print in words the hundreds, the tens and the ones (and the eventual minus) according to the rules of the English language.
• If the number is larger than 999, you must print "too large".
• If the number is smaller than -999, you must print "too small".
• If the number is negative, you must print "minus" before it.
• If the number is not built up of three digits, you shouldn't print it.

## Hints and Guidelines

We can first print the hundreds as a text - (the number / 100) % 10, after that the tens - (the number / 10) % 10 and at the end the ones - (the number % 10).

The first special case is when the number is exactly rounded to 100 (e.g. 100, 200, 300 etc.). In this case we print "one-hundred", "two-hundred", "three-hundred" etc.

The second special case is when the number formed by the last two digits of the input number is less than 10 (e.g. 101, 305, 609 etc.). In this case we print "one-hundred and one", "three-hundred and five", "six-hundred and nine" etc.

The third special case is when the number formed by the last two digits of the input number is larger than 10 and smaller than 20 (e.g. 111, 814, 919 etc.). In this case we print "one-hundred and eleven", "eight-hundred and fourteen", "nine-hundred and nineteen" etc.
