The C++ statement would be:
priority_queue<std::string, vector<std::string>, CoustomCompare> myCustomPQ;
Explanation:
To define priority queue in thst given case we need 3 template parameter; 1st parameter is the data type that would be stored within the priority queue, i.e. string here; 2nd parameter is the underlying container that would be used to store the elements ,i.e. vector of strings here; and third is the custom class for comparing the elements, here this is the given class CustomCompare. Thus the above statement is formed.
