they say not to worry about undefined etc doesnt told us about if there are two char only string xd

Closing. If you see that in your sample tests, either fix it or delete it.

If you mean JAvaScript, then it does not sound right. Both example tests and fixed submission tests have this assertion:

assert.strictEqual(removeChar('eloquent'), 'loquen');

I cannot see "eloquetn" anywhere in JavaScript tests.

In what language?

the first test is wrong so that any solution can never work. the input string has a typo, reads "eloquetn" but expects "loquen" but that can never happen by removing first and last character

Thanks!

Fixed

Added after 1 year ^^ (had to do it myself still ~~

put spoiler icon, the message is visible for people who do not decide this kata

now also on dart
"Translation Dart", "ranslation Dar"

jawa

the set-up code says

/* your solution should write the result into dst and return it */

so you should simply not use malloc because that reassigns dst to a different address
