Solution
The error messages you're seeing are due to a couple of issues in your C++ code:
-
std::countis not a member ofstd: This error is because thecountfunction is not directly under thestdnamespace. It's actually part of the<algorithm>library. So, you need to include that library at the beginning of your code using#include <algorithm>. -
Could not convert 'concatenatedString' from 'std::__cxx11::string' to 'std::vector': This error is because you're trying to return a
std::stringwhere astd::vectoris expected. You need to make sure that the return type of your function matches what you're actually returning. -
Could not convert '"Invalid input"' from 'const char [14]' to 'std::vector': This is the same issue as above. You're trying to return a
const chararray where astd::vectoris expected. Again, make sure the return type of your function matches what you're actually returning.
