maybe… but I use python 3 only…

At line 8 there’s a mistake, you should iterate i to c - 2 or more specifically (i < c - 1). Then it will get accepted.

@ssjgz yeah i didn’t considered the said test case in my code.
As pointed out by @prashant_th18 i corrected that .
Thank you both of you.

hi, actually this was right… i should have defined the flag earlier before use…
But as I was running on jupyter it must have taken the previous cell’s flag and so i didn’t get the error at my side… I corrected it now, and the issue is solved… thanks a lot!!

cin>>t;
while(t–)

string s;
cin>>s;
if(s[0]!=’<’)
{
cout<<“Error”<<endl;
continue;
}
if(s[s.length()-1]!=’>’)
{
cout<<“Error”<<endl;
continue;
}
if(s[1]!=’/’)
{
cout<<“Error”<<endl;
continue;
}
if(s.length()<=3)
{
cout<<“Error”<<endl;
continue;
}
bool res=true;
for(int i=2;i<s.length()-2;i++)
{
bool is_alpha=false;
bool is_digit=false;
if(int(s[i])>=97 && int(s[i])<=122)
{
is_alpha=true;
}
if(isdigit(s[i]))
{
is_digit=true;
}
if(!is_alpha && !is_digit)
{
res=false;
break;
}

    }
    if(res)
    {
        cout<<"Success\n";
    }
    else
