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.

**Sample Input**

18

5

**Sample Output**
