Find perfect prime numbers between 100 and 900

programming

Find the perfect prime numbers between 100-900. The so-called flawless prime number refers to a number that is itself a prime number and whose reverse number is also a prime number. For example: 113 is a prime number, 311 is also a prime number, and 113 is a perfect prime number.

Run the code:

#include <stdio.h>
int main( )
{
    int i,j,n,x,ge,shi,bai;
    for(i=100; i<900; i++)
    {
        for(j=2; j<i; j++)
        {
            if(i%j==0 && i!=j)
            {
                break;
            }
        }
        if(i==j)
        {
            ge=i/1%10;
            shi=i/10%10;
            bai=i/100%10;
            n=ge*100+shi*10+bai;

            for(x=2; x<n; x++)
            {
                if(n%x==0 && n!=x)
                {
                    break;
                }
            }
            if(n==x)
            {
                printf("%d\n",i);
            }
        }
    }
}
