how to find out that bat is the prefix of batman?

@rishaseth123 hey risha you have to make a compare function which accepts two string a ,string b
if ( (a==b.substr(0,a.length())))
return b.length()>a.length();
else if((b==a.substr(0,b.length())))
return a.length()>b.length();

   return a<b;

using inbuilt substring function you can find out the prefix
