# Convert an integer into its English equivalent.

def in_words(int)
  # Your glorious code here
end

### Test code
in_words(4)         # => "four"
in_words(27)        # => "twenty seven"
in_words(102)       # => "one hundred two"
in_words(38_079)    # => "thirty eight thousand seventy nine"
in_words(82102713)  # => "eighty two million one hundred two thousand seven hundred thirteen"

# Don't be afraid to go through multiple iterations. Don't try to solve all cases at once.
### Things to try at each iteration
# 1. Start small. Make it work up to ten.
# 2. Now bump it up to 1000.
# 3. Is it recursive?
# 4. Up to a million.
# 5. How much higher can you go? Billions? Trillions? Googol?
