my program is having problem in comparison of string no and my integer no ...a,b variables are not updating ... link to question https://www.codechef.com/problems/CHEFPDIG

#include<bits/stdc++.h>
using namespace std;


int main()
{
int t;
cin>>t;

while(t--)
{
string s;
cin>>s;

int a,b,i,f,m,l,len;
char c;

for(c='A';c<='Z';c++)
{

a=0;
b=0;

int f = c / 10;
int l = c % 10;
len=s.length();

if(f!=l)
{

for(i=0;s[i]!='\0';i++)
{
  if(int(s[i])==f)
    a++;

  if(s[i]==l)
    b++;

}
if(a>=1&&b>=1)
  cout<<c<<endl;
}

else if(f==l)
{
    a=0;
for(i=0;i<len;i++)
{

  if(s[i]==f)
    a++;
}
}

 if(a>=2)
   cout<<c<<endl;

}
}


return 0;

check this line

//   if(int(s[i])==f)

you want to check the equality of the digits...but this statement is not doing the same

int ('6')  != 6

try to run this in your compiler

char ch =6;

cout<<int(ch);

use this fact and try again :)
