The input loop repeats the `ask` code twice. In a future commit, we will
be introducing another instance of the `ask` code. This makes it
possible to mistakenly make the code to get out of sync.
Refactor the loop so that the `ask` code happens once at the top of the
loop. This introduces one functional change in the "Invalid answer" case
but it also makes it more consistent with the remaining cases.
