Qualified candidates should have an understanding of frequent capabilities like map and grep. If the candidate solves the question using one operate, ask them to resolve it using the other operate. If we find that match, then we increment the %counts hash by one, where the secret’s the date that was matched. We don’t need to initialize the values the first time a secret is found as a outcome of Perl routinely sets the worth to zero, so we can merely use the ++ operator to increment the counter for the date.

While both approach will work, a developer can be higher off using the primary technique if a quantity of values must be checked to be able to avoid looping via the array multiple times. For a one-off check, though, this is in a position to not be an issue, by which case each methods would usually be acceptable.
