Sugar Notes for C++11 (1): Tuple

I’ve switched to use C++ as primary programming language to practice algorithm problems for a while. The language still evolves these days as new standard C++14 and C++17 coming out. There’s a lot of new features and useful tools make C++11 more modern and looks like a new language compared to its old ancestor C or C++03.

I would continue to update the notes on what features I have used, for both a cheat sheet to review and a note to share, where anybody could also take a look and to see if there’s a more modern or efficient new method in C++.
