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

C++ version of the kata seems to be OK. However, it's true that is seems to be somewhat more demanding than, for example, C# version. My approach I used for C# did not pass C++ tests, I had to improve it a bit.

If you get timeouts or crashes, they are probably caused by your solution not being as efficient as you think. Compilation warnings are "just" warnings and probably do not affect the final outcome of the tests. They should be removed nonetheless.

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. :)

JS. Not an issue, you just misinterpretaded the feedback. This grid obviously has no solution, so you should have returned false. If you did, the assertion function would have returned "Passed!", but instead, your code returned an array of three elements (while 4 bulbs on the map), hence your solution is considered incorrect.

cheers

What language?

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,
