Problem 3: Assume that the input contains a list of n integers.

1. Describe an algorithm that takes as input a list of n integers in nondecreasing order and produces the list of all values that occur more than once. 2. Provide a minimum C++ class to solve this problem. That is, the least number of member functions and data members that should be included in your C++ class. 3. Provide a C++ implementation of your proposed C++ class.
