Sample tests should not have randomized inputs for

• Haskell

• Java

• JS

PHP fork, for fixing this, and (probably) this issues.

In PHP:

• Missing real fixed and sample tests

• Code for random tests should be removed in sample tests

• Actual and expected are flipped

In JS, kata did not check whether the user's result is a 1D array or a 2D array.
For example, my result looks like:

[
"OXO"
"XOX"
"OXO"
]

instead of:

[
["O","X","O"],
["X","O","X"],
["O","X","O"]
]

Description should be language-agnostic

The example from the description should be included in sample tests for all languages. Currently, most of them (if not all) don't.

The Example Test is exactly the same as the real Test Cases

There should be fixed tests in JS and the code for random tests should be removed in sample tests section.

Coffeescript

Crystal

Julia

(author inactive)

Ruby 3.0 should be enabled.

words longer than 4 letters that end in "ER" should have the "ER" trimmed off

It's not clear whether only the last "ER" has to be removed or this process should be repeated. The tests check only the former case, though.

The image in the description is dead.

No random tests in JavaScript (at least).

Is this solution only works with even numbers? Because I am having troubles with odd ones. (just like @Bugagashinka said)

Would like to ask more test scenarios and it's results.

• return of haystack array of size of 0
• return of haystack array of size of 1
• return of haystack array with no needle found

Also would like to clarrify some specifications

• array limit of haystack
• haystack objects types are limited to premitive data types?
