Question

For this assignment, you will write a program that guesses a number chosen by your user. Your program will prompt the user to pick a number from 1 to 10. The program asks the user yes or no questions, and the guesses the user’s number.

When the program starts up, it outputs a prompt asking the user to guess a number from 1 to 10. It then proceeds to ask a series of questions requiring a yes or no answer. For example:

Is your number evenly divisible by 3? (Yes or No)

The user will enter “Yes” or “No” to each question. When the program is sure it knows the user’s number it outputs the number. For example:

Your number is 9.

To receive full credit, your program must always guess the user’s number in less than five questions.

This assignment will be completed in two parts:

1. You will write and turn in properly indented pseudo-code for this assignment. Be sure you keep a copy of the pseudo-code you turn in to help you in writing the program.

2. You will create your guessing game program, and verify that it works properly on all possible inputs. Your program must be properly documented and all if and else statements must be indented properly.

I need the algorithm and pseudocode in java please
