Consider the following problems, design the algorithms that would solve them, and then implement the algorithm in Java.
You are free to choose between writing pseudo-code or drawing flowcharts. Make sure to include screenshots of your running programs. You can take screenshots using PrintScreen of the console window in which you run the program. Put your algorithm and the screenshots together in a Word document.
Problem 1:
Write a program that reads the ages of three persons from the user, and decides who is the oldest, and who the youngest person is.
Problem 2:
Write a program that reads in the name and salary of an employee. Here the salary will denote an hourly wage, such as $9.25. Then ask how many hours the employee worked in the past week. Be sure to accept fractional hours. Compute the pay. Any overtime work (over 40 hours per week) is paid at 150 percent of the regular wage. Print a paycheck for the employee.
Problem 3:
The original US income tax of 1913 was quite simple. The tax was:

1 percent on the first $50,000
2 percent on the amount over $50,000 up to $75,000
3 percent on the amount over $75,000 up to $100,000
4 percent on the amount over $100,000 up to $250,000
5 percent on the amount over $250,000 up to $500,000
6 percent on the amount over $500,000.
