Using Method Return Values

In this problem, you will implement three methods (isEven, classify, and absolute). Each method receives an argument and returns an appropriate value.

Learning Objective: Understand how to compose processing using method return values

Overview

Methods with return values pass calculation or evaluation results back to the caller. Return values can be stored in variables or used directly as arguments to other methods.

Specifications

• boolean isEven(int n): returns true if n is even, false if odd
• String classify(int n): returns "positive", "negative", or "zero"
• int absolute(int n): returns the absolute value of n

Input Format

n1
n2
n3

• Line 1: integer passed to isEven
• Line 2: integer passed to classify
• Line 3: integer passed to absolute

Output Format

result of isEven(n1)
result of classify(n2)
result of absolute(n3)

Example

Input:
4
7
-8

Output:
true
positive
8
