what

it has 2 phases like a dark souls boss

i forgot regex existed

i got confused and thought that 0x+b was possible

apparently not

how is that one only 4kyu

mfw i manually implemented an intrinsic in my solution

guess you learn something new every day

&['a', 'b', 'c'] == b"abc"

you have recreated std::cmp::Ord::max(self, other: Self) or alternatively std::cmp::max(a, b), i128::max(a, b) or simply a.max(b).
this trait is implemented for all numerical types by default and does not need to be imported.

no test for empty list? :(

Looks like the test cases didn't cover this one ;)

so close to the best one...
