nice :)

to be clear, this is not the best solution as it uses O(n^2 log n) time; Blind4Basics solution is better.

Double is used for slicing not indexing

Only way to avoid a timeout. What a dumpster-tier kata. Embarrassing for the creator.

wow!

wow how i couldn't think this way ;)

it's very simple idea and clear, big thanks

to be fair, he fixed the code. It was never specified to to keep use the same module

Just make a research with the names of the methods you don't know and you should find all the informations about it.

Someone can explain me this please? ^^

It's a solution of a programmer knowing his language.

don't you think this is a typewriter operator, not a programmer, solution?

No, it doesn't.

Here's a profile of running this problem 10 million times with an if/if/if solution versus an if/elif/else solution:

if_if_if completed 10000000 iterations
Sum time: 5684.13ms
Mean time: 568.41ns
Standard deviation: 1684.53ns

if_elif_else completed 10000000 iterations
Sum time: 5685.18ms
Mean time: 568.52ns
Standard deviation: 1642.49ns

Even if it did, if you care about nanoseconds you shouldn't be choosing different flow control syntax in Python, you should be choosing a different language.

if elif else statement works faster than if if if

rly? well, maybe it's clever but not sophisticated.

Oh boy. I really need to take a closer look to the built-in methods.
This is so obvious and I wrote like a mile of code. - Thank you for this solution.
