Create a program that calculates the union, intersection, and difference of two hard coded sets and displays the results using set notation.

Program Requirements:

Hard code the following 2 sets of 5 integers:

• A = {1, 3, 5, 6, 8}
• B = {2, 3, 4, 7, 9}.

Compute and then display A U B, A n B, and A - B.

Note: Do NOT use built-in set functions; functions built into the language to calculate union, intersection, or difference. For this assignment, you must do your own math to compute the values.

• Display the answers using set notation; comma separated elements surrounded by curly braces
  • For example: C - D = {a, c, r, t, v}
• Use a lowercase n to denote intersection, other symbols may not display properly
• Do NOT hard code the answers. They must be calculated
