The string template in C++ STL is very convenient in processing strings. To record today is how to find the specific text or substring in a string data type variable.
[C++] How to Check The Variable Data Type with typeid()
In C++, we always can be clear about the data type of the variables we declared; however, sometimes we passed in some parameters from third-party libraries, so we are not so sure which data type it is.

deque is the double-ended queue container provided by C++ Standard Template Library (STL), it is similar with vector container, but if you want to add a new element to the beginning in a vector, the time complexity is O(N), but in a deque it is O(1).
