If a String is : "Topcoder" and all of it's suffix are :

r,er,der,oder........pcoder,Topcoder

Now consider c++ code:

std::string str = "Topcoder";
const char* pointer = &str[1];
cout<<pointer<<'\n';

Output is: opcoder

What is the complexity of generating of above suffix upto 1 index of length 7? Linear or Constant ?
