Repeat String - Javascript
...sive algorithm (also called "divide and conquer") is on a string of length 123,457.

Pretty-print C++ STL containers
...sert("hello");
j.insert("world");
double k[] = { 1.1, 2.2, M_PI, -1.0/123.0 };
std::cout << i << "\n" << j << "\n" << k << "\n";
}
It currently only works with vector and set, but can be made to work with most containers, just by expanding on the IsConta...

RESTful Authentication
