luckily I solve this problem alone, but thanks for useful advices :)
have a nice day

Thanks for your reply.
I've got type, i don't know why its don't appear when i paste the code here.
Second tip doesn't help, still the SIGSEGV error occurs.
Here is a proper code:
#include
const std::vector countPositivesSumNegatives(const std::vector input)
{
int neg=0,pos=0;
if (!(input.empty()))
{
for(int i=0;i<input.size();++i)
input[i] > 0 ? ++pos : neg+=input[i];
if (!pos || !neg)
return std::vector();
else
return std::vector ({pos,neg});
}
else
return std::vector();

}
