Would add some fixed test cases for invalid board - type 2, or make them occur more in random tests.

I see solutions that don't count with them and they can still get through on luck

I know it and actually it doesnt matter if you are using fractional arithmetics as you did or rounded floats as I did

Because you are not comparing my Rounded float to your Fractions, I am comparing my Rounded floats between each other and you are comparing your fractions between each other, the number type is not the important here the order is

And even tho floats are not comparable together, they dont show any difference in the first 5 numbers after decimal point, that I use(Infact 1 would probably be enough)

So in conclusion, Yes it would work better using fractions but my way to solve this issue is also not wrong here.

Added a sentence to make it clear in describtion.

Thought its redundant.

Oh i see it. To be honest i don't know what was going through my head when i wrote that part of code.

Should be fixed.

Yeah forgot to correct the text before publishing should look better + some things should be clearer to understand

Should be fixed

Should not happen anymore

Ohh, ok interesting that i didnt trip over this kata when looking if there are duplicates

Random time wasnt a great idea, I see it now.
Made it so only the fastest solution will make it or not

yeah did not notice that its confusing
I rewrote it so its should be clear now

Sorry my first kata, random tests are now added.
