Weird grading for something this easy. I've had 5kyu that were harder (eg. the prime ant )
I agree my solution may not be "advanced Python talk" but still...

Here I thought I was gonna be a 'smart' cookie by doing quick jumps to queued positions, to make it faster.
(the distance can be up to tens or hundreds of "steps" from the lowest position)

My solution passes 1 out of 5 times, depending on the inputs.

Think i'll skip the "insane" version, looking at the other solutions i feel a python noob hahaha.

Great Kata though!

" ...it also means '00000' is definitely a short (in-character) pause, and '000000' is a long (between-characters) pause."
Yet in the "Hey Jude" example I see both 5 and 6 zero's being used "in-character"...?

in all seriousness, I agree. (the ranking and the "bad joke" :) )

3kyu are usually more difficult (for me).

I guess everything looks like a 5kyu if you're a "x dan" (compliment disguised as joke) ;-)

Great Kata!
@HKMT's one liner for compressing the grid makes me feel like a dunce... :)
(not just that but this one killed me , haha)

not the "python" way (that "compression" routine is embarracing , compared with HKMT's 1-liner) but it works...

prettyresult -> bad clean up, used for debugging...

(Python) Great Kata, but I got a feeling there's not enough random tests and hence I think my code isn't entirely full proof. (comments welcome!)

Damnit, I'm almost there. (works but times out)

I just need a formula to calculate how many combinations (wether true or false doesn't matter)

I can make of a (remaining) part of the equation, to speed up things...

I get weird numbers when I do it with the solver:
for x times True and (x-1) times & :
on the 4, 8 and 16 times True I get odd results. The rest are even.

(I only went to 16, next would have taken 10 minutes or so)

What college degree math theory am I missing here? (math noob here)

Oh well, E for Effort , I suppose ... :)

Ah no, not by a long shot,haha... i just wondered what the notation would have been.

but i do hope to make a cleaner one for what did pass, later...
