StringStream in C++ (HackerRank Solution)

Solution for StringStream in C++, one of the most popular HackerRank problem solving questions.

Learn how to use StringStream in C++ to extract formatted data from a string and store it into integer (int) or character (char) variables. Here, I am using the extraction operator with a StringStream class object in C++ to extract integers from a string and store them into a vector of integer elements. The extraction operation happens in a while loop. Knowing how to use StringStream in C++ is important for input/output operations in your programs, and also for competitive programming in C++.

why should we use (ss>>n)
in if clause? we could use it directly as
{
ss>>b;
v.push_back(b) ;
}
I don't understand why it gives wrong answer though.
