I think you should limit below 0 and upper 255

Hey. I don't know how it's in JS, but in Swift a tuple is an anonimous objest with syntax (index1: Int, index2: Int)
I also got confused with this moment. The author ment an array of ints.

Sorry, for javascript whats the difference between an array and a tuple?

yeah, totally true. No actual example in mind, mostly an almost random thought...

care to mention which exactly? sounds like domain specific use case, I referred only to general use cases

any builtin is faster...

(unless you achieve better time complexity and the inputs are large enough. Very "large enough", sometimes... x) )

i see thanks!

any builtin is faster than whatever equivalent of it you try to recreate because builtins use c implementations and skip the whole 'handling useless calls from outer layer' part

Likely because it has been highly optimized over the many years it has existed and it was probably written by someone a lot smarter than anyone here .

Generally it isn't worth it to go so deep that you are re-inventing the wheel.

My issue isnt understanding the question or solution. but i wanted to ask why is split() faster

Do you know why spliting/split() is faster than running checks in forloops?

I don't know all that much Python. I suggest you just look at the other solutions and take inspiration from them. You can even vote on which one you think is best or most creative.

Hi Dean this is python. My code works fine! but its slow for a string and for loop approach
