1 Fast and beautiful code(Using built in functions and libraries)

Using builtin functions and trusted libraries is not just a great way to reduce the amount of lines of code you'll write but it's also a lovely way to optimize your code. This is so since most of the libraries and builtin functions are implemented in another language some what faster than the one you're working with , for instance (C++). Also , the algorithm used are usually optimized algorithms. In this video i gave examples of these using some fun questions.
