Has a problem with types in php. You need to compare types of chars too. If input array has float, you must use only float in output array.

Haskell translation

Nice Kata!

• Node 18. (mocha + chai) should be enabled

• Description does not mention whether each subtable of a datatable will have only 1 field (the one used for pairing).

• Also assume each cell contains only strings or numbers (no need to test for deep equality),

  What if the expected and actual result contain 0 / 0.0 / ""...

Because there is no field for 4 in the first datatable, but it is there in the 2nd one. So, you should supply it with the corresponding number of sub values.

Approved

python new test framework is required. updated in this fork

Good one . :)

For PHP
Why did the crash test on :
[13,10,12,13,17,14,18,20,19,14]
while I send back well :
[[13,13],[10],[12],[17],[14,14],[18],[20],[19]]
is this not the expected result?

Ruby 3.0 should be enabled.
