else
cout<<1;
}
}
}
in this question one test case is passed but another is not why…
what problem is arrise in my code
Hi Vishal. First of all in this code u have not included the header files. Secondly when u are checking the condition (str1[j] = str2[j]) , here == is required while u used =. Thirdly u cant print using (cout<<0;) , u have to use “” marks (cout<<“0”;). and lastly endl is needed in end.
You can also refer to this code. I have made all the changes.
Hope ur doubt is cleared now.
