Discussion on: Daily Challenge #19 - Turn numbers into words

[morgana]

I tried to not dictionary everything, but the exceptions are real. Lots of amusing output as I got closer, that I'll paste for your enjoyment. I did actually get it working though :P

#15
fiveteen

# 818
eight hundred eightteen eight

# 101
one hundred oneteen one

# 654
six hundred six hundred six hundred

# 0 < num < 1000
