Prime Number

Time Limit: 1 sec

 

The Problem

A prime number (or a prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself. A natural number greater than 1 that is not a prime number is called a composite number.

 

For example,

5 is prime because 1 and 5 are its only positive integer factors, whereas 6 is composite because it has the divisors 2 and 3 in addition to 1 and 6.

 

Make a simple program that reads one variable named n. Print the n is prime or composite number.

 

The Input

Input file contain a series of line, each line contain 1 integer number n (0<n<10000000000). Input is terminated by EOF.

 

The Output

For each line of input, output will be "prime number" or "composite number", if n is a prime number then print "prime number" otherwise print "composite number" in a seperate line.
