Extended Confused!!!!!

Time Limit: 1 sec

 

The Problem

An integer n is said to be divisible by an integer b if n = bq for any integer q, where b is not equal to zero.

 

Example

And 10 is divisible by 5, because 10÷5 = 2 exactly

And 14 is divisible by 7, because 14÷7 = 2 exactly

But 15 is not divisible by 7, because 15÷7 = 2 ¹/₇

(i.e., the result is not an integer number)

 

Write a simple program that reads an integer number n, print “n is divisible by 5” if n is divisible by 5 or print “n is divisible by 7” if n is divisible by 7 otherwise print “Confused”.

 

The Input

There are several lines of input in the input file, and each line contains a positive integer n (0<= n <10¹⁰⁰). Input is terminated by EOF.

 

The Output

For each line of input, you have to print a line of output. If n is divisible by 5 then print “n is divisible by 5” and if n is divisible by 7 then print “n is divisible by 7”, otherwise print “Confused” without quotes. Follow the sample input/output for exact format.

 

Sample Input

21

20
