please help me provide the member function for each class in PowerString.cpp, you should only need to work on that one file, and please read the comments in the code so you know how to help me implement them in the correct ways, thank you. here are the codes.

main.cpp:

/*

*

* Purpose: To reverse each text line, say original,

* either from the specified file passing as the command line argument

* or from the user input

* and then decide if each of original,

* is a palindrome or not

******PLEASE DO NOT CHANGE THIS FILE!******
