Any help would be greatly appreciated ASAP -- First, implement a C++ function with the following signature:

std::map<std::string, unsigned int> countWordFrequencies(const std::vector<std::string>& words) 

Its input is astd::vectorcontaining a sequence of words. Its output should be astd::mapwith string keys and unsigned integer values, where the keys are the words that appear at least once in the vector and the values are the number of times each word appears in the vector.

Then, implement another C++ function with the following signature:

std::string formatWordFrequencies(const std::map<std::string, unsigned int>& frequencies) 

Its input is astd::mapwith the same meaning as the result fromcountWordFrequenciesand its job is to return astd::stringwith that information formatted in a two-column format like this.
