c++，STL部分的问题Now you have to implement a class named Expanded

Now you have to implement a class named ExpandedVector, with only one method my_reverse.

This method simply reverse the order of elements in the sequence of a vector.

For example:

v.push_back(1); // 1

v.push_back(2); // 1 2

v.my_reverse(); // 2 1

For your convenience, the data type of the elements is set to be ints.
