Palindrome

There is a typo in your example. It should be "195 + 591 = 786", not "195 + 951 = 786".

@admin

   #include<stdio.h>
2. unsigned long palin(unsigned long temp);
3. int main()
4. {
5. unsigned long a,b,c;
6. int itr=0;
7. scanf("%lu",&a);
8. while(1)
9. {
10. b=palin(a);
11. c=a+b;
12. itr++;
13. if(c!=palin(c))
14. {
15. a=c;
16. }
17. else
18. {
19. printf("%d %lu",itr,c);
20. break;

My code successfully compiles and runs on jdk 1.3 on my PC. but on the website it shows compilation error saying" compilation is successfull but main class is not found".the folowing is my code.Can someone please help.Are there any conventions for naming the main class.??  (thank you)

import java.io.*;
class palind
{
long reverse(long b)
{
long c=0;
while(b!=0)
{
c=c*10+b%10;
b/=10;
}
return(c);
}
}
class chef_palind
{
public static void main(String[] args)throws IOException
{
int i,j,n;
palind p=new palind();
BufferedReader b=new BufferedReader(new InputStreamReader(System.in));
n=Integer.parseInt(b.readLine());
long a[]=new long[n+1];
for(i=1;i<=n;i++)
a[i]=Long.parseLong(b.readLine());
for(i=1;i<=n;i++)
{
j=0;
while(p.reverse(a[i])!=a[i])
{
j++;
a[i]+=p.reverse(a[i]);
}
System.out.println(j+" "+a[i]+"n");
}
}
}

Thank you Ayush..that was so stupid of me..!!

i kno its dumb but cn anyone pls tell me how exactly to take the input?
my programme is running successfully in borland c++;

but here even though i hv used the required syntax for c++(gcc++ 4.3.2) it says wrong answer :(

// Palindrome.cpp : Defines the entry point for the console application.
//

#include<iostream>
#include<stdio.h>
using namespace std;

struct pali
{
int a,count;
};
struct pali p[100];

class pm
{
public:
int rev(int i);
int rev_a(int j);
int add(int a, int b);
private:
int n1,n2;
};

int pm::add(int a, int b)
{
int sum;
sum = a + b;
return sum;
}

goto thisplace;
}
if(n1 == n2)
{
p->count--;
cout << p->count << " " ;
return n1;
}
else
cout <<"No match ";
return 0;

oh god...cant believe this...even missing out a "n" can get one a wrong answer here..

by "n" i mean next line character

Of course it can; if you don't print any space between your answers, how could the judge know where one answer ends and the next one starts?

Should'nt this problem be in the easy section???

please check my program whats wrong in it

#include<stdio.h>
main()
{
int n,count=0,b,temp;
scanf("%d",&n);
label:
temp=n;
b=0;
while(n!=0)
{
b=b*10;
b+=n%10;
n/=10;
}
count++;
if(b==temp)
printf("%d/t%d",count-1,b);
else
{
n=temp+b;
goto label;
}
}
