Really good use of a dictionary

I did it this way because I wanted to see if it worked but this one also works: return boolean == True

I understood the idea of this approach comparing to fullsearch by removing boolean() from the result. Your solution is wonderful!

I typed same code, regards!

Use spoiler flag next time, please.

depends on the language you solve this in ;)

This is how I solved mine.

Amazing solution xD

Not done in Python, description says "and" instead of "plus".

Am I the only stupid who dont understand this solution??

yes I know google know everething but what do double question marks in your case?
