Question

You are going to write a program that allows the user to play a simple guessing game in which your program thinks up an integer and allows the user to make guesses until the user gets it right.  For each incorrect guess you will tell the user whether the right answer is higher or lower.  Your program is required to exactlyreproduce the format and behavior of the log of execution at the end of this write-up.

At a minimum, your program should have the following static methods in addition to method main:
