It's because I am using global variables and calling function multiple times! Figured it out!

got it! Seriously thanks for your immense help! I have a hard time imagining
how I would have seen that without your help!

As far as I can tell its the amount of pairs in the answer which is why I allocate the Pair** with that amount so the array of structs is that length.

Howdy all,
I'm in C. does this function

char* array2StringData(Pair** arr, int sz);

only work when the Pair** is pointing at a static array?
Because I created a dynamic array that i believe gives the correct answers
and that function is giving a {} result.

Thank you all very much!! It's working honky dory now!

Thank you, i will try and figure out how to do it withoit that. I put it there because the function calls itself and i didn't know how to retain the value.

Am I allowed to paste it here what I am doing?

I am doing this in C in Codeblocks and these test cases that my code is failing here
are generating the correct expected answers in my IED. Does it have anything to do
with the combinationUtil I am using in the code or something else?

\all distances are positive or null integers\

Hi all.
what are null integers?

Because they are initializing with these definitions:
long first = numbers[0], second = numbers[1];

size_t i = 2 means the first numbers[i] is really numbers[2].

ok, Thank you very much! Will try and be more like a carpeneter with these from now on.

no estoy seguro pero creo k si te dejan ver soluciones ajenas antes de resolverlo propiamente. creo? apenas llegue aki.
