$1$: in python: Design a queue abstract data type for float elements including operations for addition, subtraction, and matrix

multiplication.

$2$: in java: design and implement a program that defines a base class A$,$ which has a subclass B$,$ which itself has a subclass C$.$ The A class must implement a method, which is overridden in both B and C$.$ You must also write a test class that instantiates A$,$ B$,$ and C and includes three classes to the method. One of the calls must be statically bound to As method. One call must be dynamically bound to Bs method, and one must be dynamically bound to Cs method. All of the method calls must be through a pointer to class A$.$

$3$: In java: write a program that inputs a list of integer values in the range of $-100$ to $100$ from the keyboard and computes the sum of the squares of the input values. This program must use exception handling to ensure that the input values are in range and are legal integers, to handle the error of the sum of the squares becoming larger than a standard integer of the result. In the case of an overflow of the sum, an error message must be printed and the program terminated.
