The main function creates 5 pixels with random red, green, and blue values. Complete the id_color function to return “red” if the red value is greater than the green and blue, “green” if the green value is greater than the red and blue, and “blue” if the blue value is greater than the red and green. If there is no clear maximum value (for example, if the red and green values are the same) return None. Do not change the main function.
import image
import random
def id_color(p):
'''Returns the dominant color of pixel p'''
pass
#Your code here to determine the dominant color and return a string
identifying it
#Hint: get the red, green & blue values and use an if statement
to determine which has the highest value
def main():
'''Controls the program'''
for i in range(5): #Loop 5 times
r = random.randrange(0, 256)
g = random.randrange(0, 256)
b = random.randrange(0, 256)
print(r, g, b) #Show the pixel red, green & blue values
new_pixel = image.Pixel(r, g, b)
print(id_color(new_pixel))
main() #Run the program

First, launch NetBeans and close any previous projects that may be open (at the top menu go to File ==> Close All Projects).
Then create a new Java application called "BackwardsStrings" (without the quotation marks) that:
So, for example, if the first string is 'usr' and the second string is 'bin', your program would output something like the following:
The two strings you entered are: usr bin. The two strings in reverse are: nib rsu.
Note that the reversed SECOND string comes FIRST when printing the strings in reverse.
This program must be completed without using loops and without using StringBuilder.
See Horstmann pp. 62-63 for some ideas. Make sure your program includes the command line prompts for the user and that it formats the output appropriately.
Be sure both input strings are three characters in length. If this data validation isn't passed, output "Invalid string length for one or both inputs." and do not proceed with further processing of the strings.

Write a program 'Rectangle-Area.c' that inputs the length and width of a rectangle and outputs its area. The program consists of two functions: the main function and a function that computes and returns the area of a rectangle. The output of the program should be in the main program, not in the function.
Sample Input: 5 8 Sample Output: The area of a 5 by 8 rectangle is 40.

Write a script which receives a list of parameters. If no parameters are received, output an error message. Otherwise, iterate through the list and, using a case statement, test each item in the list to see if it starts with a capital letter, lower case letter, digit or other. Count each type and output at the end the total for each category (capital, lower case, digit, other).

First, launch NetBeans and close any previous projects that may be open (at the top menu go to File ==> Close All Projects). Then create a new Java application called "PasswordChecker" (without the quotation marks) that gets a String of a single word from the user at the command line and checks whether the String, called inputPassword, conforms to the following password policy. The password must: Be exactly three characters in length Include at least one uppercase character Include at least one digit If the password conforms to the policy, output "The provided password is valid." Otherwise, output "The provided password is invalid because it must be three characters in length and include at least one digit and at least one uppercase character. Please try again." Some other points to remember... Do not use a loop in this program.
The Character class offers various methods to assist us in finding a digit or cased letter. Remember to press "." to locate these methods and to leverage the online resources shown in our course thus far." For this PA, do not use pattern matching (aka "regular expressions").

Inheritance – Address, PersonAddress, BusinessAddress Classes
Assignment
Download the Lab6.zip starter file. Use 7zip to unzip the file using ‘Extract Here’. Open the project folder in IntelliJ.
Examine the Main and Address classes. You are going to add two classes derived from Address: BusinessAddress and PersonAddress.
Create BusinessAddress class
The printLabel method should print (using System.out.println()) // Here is the 1st place I'm getting stuck ?? All I did was create the BusinessAddress class. I appreciate your assistance
First line – the businessName field
Second line – the address2 field if it is not null or empty
Third line – the StreetAddress field if it is not null or empty
Fourth line – city field followed by a comma and space, the state field followed by two spaces, and the zip field
Create PersonAddress class
The printLabel method should print (using System.out.println())
First line – the personName field
Second line – the StreetAddress field
Third line – city field followed by a comma and space, the state field followed by two spaces, and the zip field
Modify Main class
Add the following three BusinessAddress objects to the list.

BusinessName |
Address2 |
StreetAddress |

Write a C program to run on unix to read a text file and print it to the display. It should count of the number of words in the file, find the number of occurrences of a substring, and take all the words in the string and sort them (ASCII order). You must use getopt to parse the command line. There is no user input while this program is running.
Usage: mywords [-cs] [-f substring] filename
• The -c flag means to count the number of words in the file. A word would be a series of characters separated by spaces or punctuation. A word could include a hyphen or a single apostrophe.
• The -s option means to print the words in the file sorted by ASCII order.
• The -f option will find the number of occurrences of the given substring.
• You may have any number of the flags included or none of them.
• The order they should be run would be: -s first, -c second, and -f third.
--------------------------------------------------------------------------------
Format of parsing the command line (main method established), rest of functionality needed as explained above:
int value = 0;
int main(int argc, char **argv) {
extern char *optarg;
extern int optind;
int c, err = 0;
int cflag = 0, sflag = 0, fflag = 0;
char *substring;
// usage
static char usage[] = "usage: mywords [-cs] [-f substring] filename";
while ((c = getopt(argc, argv, "csf:")) != -1)
switch (c) {
case 'c':
cflag = 1;
break;
case 's':
sflag = 1;
break;
case 'f':
fflag = 1;
substring = optarg;
break;
case '?':
err = 1;
break;
}
if (fflag == 1) {
printf("%c ", substring);
}

Modify the MergeSort program given to support searching subarrays.
Program is listed below in Java.
public class Merge
{
public static void sort(Comparable[] a)
}
Comparable[] aux = new Comparable[a.length];
sort(a, aux, 0, a.length);
}
private static void sort(Comparable[] a, Comparable[] aux, int lo, int hi)
{ //Sort a[lo, hi)
if (hi - lo <= 1) return;
int mid = lo (hi + lo) / 2;
sort( a, aux, lo, mid);
sort(a, aux, mid, hi);
int i = lo, j = mid;
for (int k = lo; k < hi; k++)
if (i == mid) aux[k] = a[j++];
else if (j == hi) aux[k] = a[i++];
else if (a[j].compareTo(a[i]) < 0) aux[k] = a[j++];
else aux[k] = a[i++];
for (int k = lo; k < hi; k++)
a[k] = aux[k];
}
public static void main(String[] args)
{ }
}
Note: The user would give an unsorted list of words as command-line arguments along with the starting and ending index of the subarray that should be sorted. The program should print out a list where the strings between the given indexes are sorted alphabetically.
Sample runs would be as follows.
>java MergeSort 2 4 toy apply sand bay cat dog fish
toy apply bay cat sand dog fish
>java MergeSort 0 3 was had him and you his the but
and had him was you his the but

Typed please.How can we implement efficient search operations? In this area, we will discuss various algorithms, including sequential search, sorted search, and binary search. The characteristics of these algorithms will be analyzed, such as the running times and the type of lists they can be used with.
