Alright! Thanks for replying :)
now that i can be certain, i'll try to minimize my memory usage.

Following these warnings - I've tried both recursive and iterative solutions (both sufficiently efficient)
on my local machine and they both seem to work on all test inputs while on codewars the tests keep crashing..
I get either a double-free corruption or a stack-overflow, please someone let me know if its a bug or not.
Thanks anyways!

Not sure if its an issue but the c++ tests seem to produce warnings that isnt in my code:

main.cpp:62:30: warning: comparison of integers of different signs: 'int' and 'std::vector::size_type' (aka 'unsigned long') [-Wsign-compare]
for(int i = 0; i < coins.size(); i++)
~ ^ ~~~~~~~~~~~~
main.cpp:63:37: warning: comparison of integers of different signs: 'int' and 'const unsigned int' [-Wsign-compare]
for(int j = coins[i]; j <= money; j++)

First of all thank you for the fast response!!
I assure you i did not reported this issue so easily i guess besides that "false"
(which i tried before) something else is slightly wrong with my solution. :)

There seems to be something wrong with the tests, i always get like 100+ success and some 5-8 fails that always look like they should be false
but it claims it has at least one solution: (no spoilers)

take a look and tell me this one has a solution please,
