Nice code , but asprintf is not part of the standart library of C lenguage, saing that, can give sa¡ome issues on windows.

Cute, but this is GCC, not C. Also the format of (n-1) using %d is not portable since %d requires an int but n is a (size_t).

so it won't work on smth like msvc

not standard -_-

Practice more. ;)
This is not the kind of thing you'll learn in a book.

Completely agree with you, prbsh9, I thought the same thing. Spent a bit of time answering the question that was posed, only to find out it was a waste of time because the solution requires a completely different approach. Apparently, we're supposed to be mind readers. I'm glad I answered the actual question that was asked correctly; just a shame I have to press 'skip' now.

What the heck........................ Why dont you include some of the jumbled and shity examples like 826591414YV}AeejE755373346AT}}27l12456100629s12989B20#^rfr51968p62 in the sample test and description.......... Spent hours thinking a method and now everything is freaking useless. If the random test are so like f--k... why is not the sample and description........... Seeing the description and sample test it feels like it would come only alphanumeric and first text then numbers...

Someone learn how to waste others precious time............... TEACH ME IF I AM NOT GETTING SOMETHING OR EVERYTHING IS JUST LIKE THIS

How the heck do these ideas appear.... Any suggestion except practice more ? This is so brilliant man.

Thanks

Add a print statement in your code to know the arrays.

Sorry, I am beginner or what but i dont understand where to print the input.. I did not understand.. What did you mean ?

Print the input.
Post only once the same question.

Cant I see exit code and question of which I got it wrong ??
I see like I got 3 wrong but I dont know what got me wrong.. What was the array1 and array2 which got me wrong ? ....

Just now realized I forgot to add the freaking return statement...
