--explanation--

Sophie says, You should have used a while loop.

Should have + Past Participle is used to talk about a mistake or something that should have been done differently. For example:

• I should have studied more for the test. - You didn't study enough, and that was a mistake.

• You should have called me earlier. - Someone didn't call you earlier, and you think they should have.
