You're wrong @gtrstr, sum does work with booleans, you can try executing sum([True, True, True]) in Python to see it evaluates to 3.

Boolean values are the two constant objects False and True. (...) In numeric contexts (for example when used as the argument to an arithmetic operator), they behave like the integers 0 and 1, respectively.

But if anagrams are case sensitive, then why are Buckethead and DeathCubeK true anagrams according to the C++ test cases?

I might do a version two at some point, Thanks for the idea!

Note: anagrams are case insensitive

Wasn't that there 3 days ago?
