C++ Implement the Merge and MergeSort methods in the HeroesDB class. Declare your method in the HeroesDB. h file and define the method in the HeroesDB. cpp file (C++ Class Methods ( ) ) . Your code must follow the pseudo-code. NOTE: you must add a parameter of type SortBy to both methods. Case 2 in the main method in HeroesV2. cpp already has code to get the user's sort by selection. Pass it to the SortByAttribute method that you'll create in part A-2. NOTE: in Merge, you'll need to Compare heroes. Use the static Hero Compare method.
