Get started with STL in C++! Explore various inbuilt functions and algorithms of a container and feel their ease and efficiency in coding.

In this problem set, you'll be introduced to the following containers.
1. Vector
2. Stack
3. Queue
4. Deque

The problems in this problem set require you to write a script in C++ using the required STL and process the data in standard input and output. Except for one problem where you just need to implement the given structures and functions.
