Problem Statement

Task: create interface Computation and a class Add that implements it.

Input Format

Two integers a and b

Output Format

Sum of a and b

Example

10 15
25

Constraints

• Use interface

• Class must implement the interface

Concept Explanation

An interface defines a method without body.
Class Add implements that method and provides logic for addition.

Step-by-Step Explanation

1.Create interface Computation.

2.Declare method compute(int a, int b).

3.Create class Add that implements Computation.

4.Override compute() method.

5.Return a + b.
