agree to disagree. As I see your point of view valid I also think of it like this: Ok, I know how to permuate a list with itertools, but it's crucial for me to know what exaclty permutation is and how the alghoritm look like

lol, Gemini generated

Please read the issue posted above. Understanding the flaw, you can re-write and re-submit your code.

Best of luck!

Python (at least):

Random Tests are not guaranteed to fail a faulty solution such as this one that fails to account for upper / lowercase counting as the same char, as shown the 3 test cases below.

input  ' iwDwW59viI;LMxADnEc5XMCVVrX3hp0u '
result 'W' should equal '9'

input  'f.FGP1.H59u n3'
result 'F' should equal 'G'

input  'peLiEWOfbS,Brl1PsUcBgmaRnMShh5q8osKoyziKTvjv'
result 'E' should equal 'W'

Instructions are unclear

How do i make rendom tests?

As far as I can tell, this doesn't hurt performance. You'd still have to do a full pass regardless; thus, you can't stop.

bruh moment

gigacahd

i did the same honestly

im sure thats what they use in production code
