I have no good candidates to retire here. All kata have identical main task, and differ when it comes to handling ties, in a way which can be potentially interesting in a low-level kata. But is it? No idea. 1. is the simplest and has most languages, 3. is (i think) the most complex.

• retire 2 (no random tests / 1 language only / most basic version of the task)
• 4 is the only one that is "up to date", considering how the tests are written, so I think we should make this one survive.
• between 1 and 3, keep 1. 3 seems more artificial and has only 1 language.

Summary:

• keep 1 and 4
• retire 2 and 3

I vote to keep 1 based on having the most languages. Retire the rest

vote for keep 1

[hobovsky]

No one wanted to keep 2. or 3., so they get retired.
Everyone agreed to keep 1., so it stays.
There is some opinions to keep 4., so it stays.
