OP solved it, closing

ruby:

For ‘abc def’ it expects ‘af1be2cd3’ but the error I am now getting is “Should work for two words, like 'CodeWars Rocks' - Expected: ‘Cs1ok2dc3eo4WR5a 6rs7’, instead got: ‘Cs1ok2dc3eo4WR5as6r’”

Why is ‘CodeWars Rocks’ considered two words, but not ‘abc def’? Is it the capital letters??

Approved

Updated JavaScript

• Updated to Node 18
• Chai for tests
• Removed global variables from random tests

I'm also in Ruby and passing the normal tests and then getting errors on the "random strings." The test says its expecting an empty string which doesn't make sense...... ("")

I think this kata is kinda confusing, because of how to input digits symbols, etc..

Approved by someone

Python update (new testing framework)

Same issue here lol. Should work for random string too - Expected: "", instead got: "jn11h2su3114vp5"

That's funny, I'm having a problem with the random tests in Ruby too, but whereas yours expected just a small part of the string, mine expected an empty string:

Should work for random string too - Expected: "", instead got: "1p1am2ge3we43v5gf6u37st8fi97w10fv11w412r6135j14an15is16ak17ki180s19"```

I have a solution which passes normal test cases but fails on random strings during submit. Here's the message I get:

Testing String citpr8cpqctev04hl12y80rij
Should work for random string too - Expected: "cj1", instead got: "cj1ii2tr3p04r858y6c27p18ql9ch10t411e012"

Is it me getting the kata in a wrong way, or is there a bug in tests? (Language used - ruby).

You mean something like this?

A wonderfully simple and optimizable problem. Good job!

You could add a more annotated example to make things super clear, though. It's hard to describe "2 from the left, 2 from the right" and so on. Here's an example; you can use it if you wish.

charConcat("abc!def")
//          ^     ^    // 0 from the left, 0 from the right
//          a     f  1 // plus the iteration number
//          -^   ^-    // 1 from the left, 1 from the right
//           b   e   2 // plus the iteration number
//          --^ ^--    // 2 from the left, 2 from the right
//            c d    3 // plus the iteration number
//          ---^---    // central character is ignored
                      === 'af1be2cd3'
