Deduplicate - count ones in binary

[hobovsky]

1. Count the Ones

• 7 kyu
• The task mentions that conversions to string are restricted, but no translation except JS enforces it.
• Satisfaction 90%, 2k solutions
• 5 pending issues
• 4 languages + 2 pending translations
• Published Apr 2015, author inactive.

2. Bit Counting (many languages, high completion, overranked at 6kyu)

• 6 kyu
• Satisfaction 88%, 137k solutions.
• 3 pending issues.
• 24 languages + 2 pending translations.
• Published Oct 2013, author inactive.

inb4 "rerank 2.": due to significant amount of solutions, reranking 2. most probably won't happen now.

EDIT: after some time, another kata was found by akar-0. Please see #89. (retired)

Both have missing random tests in some languages. So both are going to require maintenance.

I have no preference. Well, don't throw away more than a literal ton of solutions I guess.

[ejini6969]

Me neither. I'm more prefer to keep the latter since the solutions of that one are a subset of the former (even though the no string requirement is enforced), but since reranking is difficult at this stage, I have no other suggestions on what to do next.

retire 2 and remove restrictions from 1.

Ranking of 1 is more appropriate, and has less languages, so less modifications to do.

[monadius]

Retire 1 since it has only 4 languages. This task is quite interesting in languages which are missing in 1 (C, NASM, COBOL, etc.). There should be no restrictions.

[CiprianAmza]

I would keep only 2 as there are way more translations and more solutions.

[Blind4Basics]

the missing languages could be transfered to the 7kyu, couldn't they?

[ejini6969]

The thing is, the first one has restrictions and if it is decided to stay, it can be troublesome to enforce across all languages, and if no restrictions, existing languages have to be modified. So, not just translation migration ~~

[Blind4Basics]

retire 2 and remove restrictions from 1.

:whistling:

[akar-0]

Like monadius I think it's better and easier to keep 2 and remove 1. Restrictions on 1 are irrelevant IMO, and would be hard or impossible to apply in some languages. It's true a fair rank would be rather 7kyu but I think the benefit doesn't justify the cost.

[Blind4Basics]

why do I feel like nobody is reading my suggestions...?

what about removing those damn restrictions in 1??

[monadius]

Who is going to move 20+ languages from 2 to 1? I would like to change the retirement process: 1. Move all languages from the kata to be retired first. 2. Retire kata.

[Blind4Basics]

but is that a so big problem to lose some or even most of those languages? other users can still add them later if they want. The 6 kyu is beyond recovery about the rank, considering the number of completions. This is our only shot to balance this (edit: well, there is one single other option after that: retiring the 6kyu. But after the 7kyu got reitred!??). Imo, a bit more consistency is better than 20 languages where at most 100 users (overall) were involved in (not sure that sentence is correct... Pretty sure it isn't... 'hope it still conveys the idea).

[monadius]

I don't care about the rank at all: there is no big difference between 6 kyu and 7 kyu (especially considering that many old kata are overranked). Available languages are substantially more important. And we are not talking about 1-3 languages here.
