Your logic seems fine to me, make sure while submitting your solution you’re selecting language(c (gcc6.3)
All you need to do is change the line - if(c % 10 == 0)
to if(c % 10 != 9)
.

It will answer your question.
Consider this test case:
A = 5891 and B = 5890
You code will output ‘0’.
I suppose correct answer will be 2 as a single ‘0’ can be counted as a leading zero and as per the constraints Leading zeros are not allowed.
Here is your AC solution: https://www.codechef.com/viewsolution/15383641
Hope this helps!
import java.lang.*;
class sub
{
int a,b,res;
void getdata(int A,int B)
{
a=A;
b=B;
}
void show()
{
res=a-b;
res=res-1;
System.out.println(res);
}
}
class sample
{
public static void main(String args[])
{
sub s=new sub();
s.getdata(5858,1234);
s.show();
}
}
whats wrong in that???
You are allowed to vary answer by only 1 digit. Say you got res=a-b=100. Then res-1=99 vaires on all 3 digits instead of just 1.
