1. (13 points) Think about the full object-oriented version of the CORE interpreter that we've discussed in class. Suppose we wanted to use polymorphism in the implementation of the Stmt class. That is nstead of having a Stmt class that is a container for another node type (Assign, In, Out, If or Loop) we want to have Stmt be an abstract class that defines the methods parse, execute and print. Assign, In, Out, lf and Loop will be derived classes of the Stmt abstract class. (In Java terminology, Stmt will be an interface and the others will be classes that implement the Stmt interface, in C++ terminology Stmt will be a purely abstract class containing only virtual methods) Provide in pseudocode or in Java or C++ a definition of the abstract class/interface Stmt mplementations of the classes derived from Stmt (including their parse, print and execute methods) and the implementation of the StmtSeq class that Stmt stra bars for eg ons od will
