if you put a space wrong in the output string then it wouldn't be correct any more, that should be entirely unsurprising x)

maybe you'd argue that a space doesn't matter because a human might not see it. but some humans would see it, or it would look weird in some situations. there's also nothing special about space - the problem description doesn't mention words (or more to the point, word separators, space), and if you have logic in your code that is doing things that aren't related to the problem then that might immediately be a hint that it is not the correct thing to do. you could have other characters missing or added, ones that you would see. wrong spaces might also wreak havoc in other parts of a program that relies on disemvowel to behave correctly.

are you guys telling me there is like a million diffrent ways to frase this? why does it fail if I put a single space in the wrong spot then? coding sucks.
