Problem Solving: Submit class diagrams, source code and screenshots using blackboard. Using C++ create a menu-driven program that solves the following problems: The Adder computes the sum of the numbers in a given array. For example: given [9, 6, 3), the function should return 18. The Mixer combines two arrays by alternatingly taking elements. For example: given the [9, 8, 7] and [1, 2, 3], the function should print [9, 1, 8, 2, 7,3). The Sorter arranges an array of numbers such that they form the largest possible number. For example, given [50, 2, 1, 9), the function should return 95021.
