Hello I need help with a c++ function for my project involving vectors. Here is the RME for it

//REQUIRES: v is not empty //EFFECTS: returns a summary of the dataset as (value, frequency) pairs // In the returned vector-of-vectors, the inner vector is a (value, frequency) // pair. The outer vector contains many of these pairs. The pairs should be // sorted by value. // { // {1, 2}, // {2, 3}, // {17, 1} // } // // This means that the value 1 occurred twice, the value 2 occurred 3 times, // and the value 17 occurred once std::vector > summarize(std::vector v);

And these are the libraries I can use what the stub looks like:

#include #include #include #include #include

vector > summarize(vector v) { return { {} }; // avoid Visual Studio error "function must return a value" }

Also I have access to this sort function

void sort(std::vector &v);

Thanks!
