Please don't post solutions in Discourse.

Same issue in C.

@hobovsky noted this issue 5 years ago to think about, but perhaps they are still thinking :D

The C++ Description incorrectly states that for examples 1 and 3, the outputs should be: 9.2 and -2.398, even though the function returns an int.

nope, the problem description includes this:

Assumptions

• You can assume that you are only given numbers.

if we're ever passed a list that includes non-numbers, it's the code calling our function that's breaking the contract, not us

Perl translation

kata solution != kata suggestion.

Also do not post solutions in discourse, let alone not marking the spoiler flag

Didn't we have to consider that array element could be not a number?

Merged, and arrow functions seem to work now.

The kata is currently in version 7.0 but arrow functions were introduced in 7.4.

I made this fork updating the kata to version 8.0. Please review before approving, this the first time I do php.

I agree bobo kasi gumawa ng instruction nayan

:P
