Ineed writing this function. i'm not too familiar with vectorslanguage: c++//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 oncestd: : vector > summarize(std: : vector v); we are also given a sorting function that sorts the vector from smallest to largest number.//modifies: v//effects: sorts vvoid sort(std: : vector & v);

Assume the existence of a bankaccount class. define a derived class, savingsaccount that contains two instance variables: the first a double, named interestrate, and the second an integer named interesttype. the value of the interesttype variable can be 1 for simple interest and 2 for compound interest. there is also a constructor that accepts two parameters: a double that is used to initialize the interestrate variable, and a string that you may assume will contain either "simple", or "compound", and which should be used to initialize the interesttype variable appropriately. there should also be a pair of functions getinterestrate and getinteresttype that return the values of the corresponding data members (as double and int respectively).
