**Write a program to check whether a given number is circular prime or not**

**Note:Â **A number is said to be aÂ circular primeÂ if all its possible rotations are also prime numbers.**Example:Â **113 is a circular prime since 311 and 131 are also prime**Input Format**

The input contains an integer

**Output Format**

Print CIRCULAR PRIME or NOT CIRCULAR PRIME

**Sample Input 1**

3119

**Sample Output 1**

CIRCULAR PRIME

**Code:**

```
# include <stdio.h>
# include <stdlib.h>
# include <stdbool.h>
# include <math.h>
int flg;
void chkPrime(long int n)
{
long int i;
i=n-1;
while(i>=2)
{
if(n%i==0)
{
flg=1;
}
i--;
}
}
void AllCombination(long int a)
{
long int b1,c1,d1,e1,i,j,k,s1,z1,v1,x[8],y[8],m;
b1=a;
i=0;
while(b1>0)
{
y[i]=b1 % 10;
b1=b1/10;
i++;
}

}

while(m>0)
{

d1=i-1;
e1=0;
s1=0;
while(e1<i)
{
z1=pow(10,d1);
v1=z1*x[c1%i];
c1++;
d1--;

}

}

if(flg==0)
{

}
else
{

}
return 0;
