Thanks!

emmmm, sorry ....o_o

TypeScript:

The code passes all basic tests upon “testing“. Once attempting, the basic test fails because of an undefined entry in the returned array, while the random tests all pass.

Any hints?

Read the description again.

In the second test

{
        char* arr1[7] = { "cod", "code", "wars", "ewar", "pillow", "bed", "phht" };
        char* arr2[8] = { "lively", "alive", "harp", "sharp", "armstrong", "codewars", "cod", "code" };
        dotest(arr1, 7, arr2, 8, "{'cod','code','ewar','wars'}");
}

The corect return is "{'cod','code','ewar','wars'}" , why not "{'cod','code','wars','ewar'}" ?

I'm be beat by integer and surrender to float ( ╯□╰ )

I like your code!

you too!

amazing
