hmmmmm...

Same, it's tragic that the testing framework's It macro makes including <range/v3/all.hpp> impossible. Any brevity you are able to achieve is offset by the gazillion lines of import above it :(

😄 Perfect C++20/23 !!

But you know what : I'm tired with 30mns trying to figure out which include I have to use in rangev3 for each algo/view/.. and line of code !!

😃

actually this is incorrect and will fail in some random tests, but it passed...

would you please give some explaination? XD

yes, just realized the sign bit and '\0', thanks for your reply

your buffer is not large enough, and as a result you are writing out-of-bounds and corrupting the tests suite.
note that printf("%d", INT_MIN) == 11

i got you must return the given string error msg in random test,

need i consider the realloc?

emmm... i feel like a fool.

Look at begining of your function. Empty array is {}

{{}} - array containing 1 empty array.
