Difference of two sets: • A set is an unordered collection of unique elements. • The set may contain different types of data; it can be numbers, characters, strings and also class objects. • Difference of two sets is the removal of elements from one set that are common in another set. • Thus, if difference is taken between“set1” and “set2”, then the common elements of “set1” and “set2” will be removed from “set1”. • In Python, “-” operator or “difference()” method can be used to find the difference of two sets. • The difference operation is not symmetric; thus, interchanging of operand sets will produce different results.

Program Plan Intro

Difference of two sets:

• A set is an unordered collection of unique elements.

• The set may contain different types of data; it can be numbers, characters, strings and also class objects.

• Difference of two sets is the removal of elements from one set that are common in another set.

• Thus, if difference is taken between“set1” and “set2”, then the common elements of “set1” and “set2” will be removed from “set1”.

• In Python, “-” operator or “difference()” method can be used to find the difference of two sets.

• The difference operation is not symmetric; thus, interchanging of operand sets will produce different results.

1.[30 pts] Computers generate color pictures on a video screen or liquid crystal display by mixing three different colors of light: red, green, and blue. Imagine a simple scheme, with three different lights, each of which can be turned on or off, projecting onto a glass screen: We can create eight different colors based on the absence (0) or presence (1) of light sources R,G and B: R G B Color 0 0 0 Black 0 0 1 Blue 0 1 0 Green 0 1 1 Cyan 1 0 0 Red 1 0 1 Magenta 1 1 1 0 Yellow 1 White 1 Each of these colors can be represented as a bit vector of length 3, and we can apply Boolean operations to them. a. The complement of a color is formed by turning off the lights that are on and turning on the lights that are off. What would be the complement of each of the eight colors listed above? b. Describe the effect of applying Boolean operations on the following colors: Λ 1. Red(100) ^ Magenta(101)= Blue(001) 2. Bue(001) | Green(010)= 3.

Methods (Ch6) - Review 1. (The MyRoot method) Below is a manual implementation of the Math.sqrt() method in Java. There are two methods, method #1 which calculates the square root for positive integers, and method #2, which calculates the square root of positive doubles (also works for integers). public class SquareRoot { public static void main(String[] args) { } // implement a loop of your choice here // Method that calculates the square root of integer variables public static double myRoot(int number) { double root; root=number/2; double root old; do { root old root; root (root_old+number/root_old)/2; } while (Math.abs(root_old-root)>1.8E-6); return root; } // Method that calculates the square root of double variables public static double myRoot(double number) { double root; root number/2; double root_old; do { root old root; root (root_old+number/root_old)/2; while (Math.abs (root_old-root)>1.0E-6); return root; } } Program-it-Yourself: In the main method, create a program that…
