[PII015] Leap Year

A leap year contains one extra day, having a total of 366 days.

A year is said to be a leap year, if the year is exactly divisible by 4 but and not divisible by 100. It is also a leap year if it is exactly divisible by 400.

The Problem

Write a program that, given a year, finds out if it is a leap year or not.

Input

The input consists of one line containing one integer Y indicating the year to consider.

Output

The output should be a single line displaying "Y is a leap year" (if it is a leap year) of "Y is a normal year" (if it is not a leap year).

Constraints

The following limits are guaranteed in all the test cases that will be given to your program:

1 ≤ Y ≤ 5000       Year to consider

Example Input 1 Example Output 1
2025
2025 is a normal year

Example Input 2 Example Output 2
2008
2008 is a leap year
