C# random tests almost always expect
falsePHP translation
C translation
C++ translation
Rejected by someone, refer to comments in translation discourse and create a new fork as a fix
Julia translation
Approved
COBOL translation.

Ruby 3.0 should be enabled.
done
You should mention that input may be negative (at least in Python).
fixed
java translation added ;)
Applied some improvements and approved.

i can not do proclonic number example
I suggest you to extend the test suit of this Kata in Ruby, it's passing with no problems for the non-positive numbers, which actually cannot be Pronic as (-5) * (-6) is not -30 ;-)
There are already fixed tests with negative numbers, your solution will also return
false(which is correct) forn = -5/n = -6because whenx = 2,-6 != 2 * 3for both cases above.C# translation kumited!
I'm pretty sure that there's a duplicate of this kata… However, it could take a while to find it. The other one definitely didn't call the numbers "pronic".
Even I also think so :-| And as it was not easy to find one so I created this kata :-)
Why is that we have very few solvers of Figurate Numbers #1 - Pentagonal Number??
Please don't use
>for indentation. It's meant for quotes.Ok :) But is it a thumb rule? & I just used it to make comment prettier.
Yes. It creates a
<blockquote>element. It's meant for email-style quoting.Random notes: training on pronic numbers is good, testing it on every kind of Object and prototyping a method for this a tad less.
Also, most of the random tests (like 98% or so) seem to return
false, so I would work on that too.Any help how can I get biased random number???
Just two calls of
random. First decide if the next number will be be pronic then generate this kind of number.Precisely what I did :)
Now is fixed :)
