Summary: Given integer values for red, green, and blue, subtract the gray from each value.
Computers represent color by combining the sub-colors red, green, and blue (rgb). Each sub-color's value can range from 0 to 255. Thus
(255, 0, 0) is bright red, (130, 0, 130) is a medium purple, (0, 0, 0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray. (130, 50,
130) is a faded purple, due to the (50, 50, 50) gray part. (In other words, equal amounts of red, green, blue yield gray).
Given values for red, green, and blue, remove the gray part.
Ex: If the input is:
130
50
130
the output is:
80 0 80
Find the smallest value, and then subtract it from all three values, thus removing the gray.

Write a program that prompts the user to input any digit then swap the position of the first and the last digit. Next, the user will be prompt to select what arithmetic operation he/she want to employ on the first and last digit based on the following choices:
1. Sum of their square
2. Product of their square root
3. Square of their product
The output will display the result of the arithmetic operation followed by the digit with a swapped position of “first” and “last” digit. Then finally display the equivalent uppercase alphabet for the first digit and lowercase alphabet for the last digit respectively after swapping.
Note:
1. If the last digit of the inputted digit from the user is zero, it must display that there is no equivalent alphabet for that digit.
2. If the user chooses arithmetic operation No.2, format the output to three decimal places
TEST CASES:
If a user inputs a digit and choose arithmetic operation No.1:
Input any number: 97834

Their equivalent resistance Reg is related to the values R1, R2, ..., Rn by: 1 1 1 1 + +...+ R R R, R. "eq Write a program that prompts the user to enter the resistance of n resistors. The user should be prompted continuously by using a while loop until a zero or negative value is entered (the program should count the number of resistors n entered by the user and store the values in an array). Use another separate loop to print the resistance values entered by the user and the equivalent resistance Reg.

- Write a program that reads an integer and displays all its smallest factors, also known as prime factors. For example, if the input integer is 120, the output should be as follows: 2, 2, 2, 3, 5arrow_forwardTask Write a MASM program that will resemble a digital clock. The clock will display hh:mm:ss (hour, minute and second format; 2 digits for each), i.e., 03:10:05. The clock will take an input from the user (0 to 9) which will be the starting time of the clock. Say the input is 6, so the clock start time is 00:00:06. 00:00:59. You increment the second by one, i.e., 00:00:06, 00:00:07, Then you need to change the minute to 01 and second to 00, i.e., 00:01:00. Similarly, change the time for hour e.g., 00:59:59 will change to 01:00:00. It is a 12 hour clock. After 11:59:59, the clock will change to 00:00:00. You may like to run the attached Calcul.exe to understand the expectation. ● Commenting Most of the lines of the program code should be commented (short comment is fine) so that your code could be well understood.arrow_forwardWrite a program that performs as a very simple calculator. Your calculator should be able to handle the four basic math operations — add, subtract, multiply, and divide — on two input values. Your program should prompt the user to enter three arguments: two double values and a character to represent an operation. If the entry arguments are 35.6, 24.1, and '+', the program output should be The sum of 35.6 and 24.1 is 59.7.arrow_forward
- Write a program that uses a random number generator to generatea two digits positive integer and allows the user to perform one or moreof the following operations:a. Double the number.b. Reverse the digits of the number.c. Raise the number to the power of 2, 3, or 4.d. Sum the digits of the number.e. If the number is a two digits number, then raise the first digitto the power of the second digit.f. If the number is a three digits number and the last digit is lessthan or equal to 4, then raise the first two digits to the power ofthe last digitarrow_forwardWrite a program to read the radian of a circle, check if it is bigger than zero, and if it is to calculate and display the perimeter of the circle using the formula P=2*3.14*R, where P is the perimeter and R is the radius of the circle. Otherwise it should prompt for the radius again until it is bigger than zero.arrow_forwardWrite a program that reads the length and width of a rectangle as integers from the keyboard and then calculates and printsa) the area of the rectangle, andb) The circumference of the rectangle.arrow_forward
- Write a program that reads a floating point number and prints "zero" if the number is zero. Otherwise, it prints "positive" or "negative" (as appropriate). Add "small" if the absolute value is less than 1, and add "large" if the absolute value is greater than 1000.arrow_forwardWrite Java program that randomly generate two Integers between 1 and 10 as input and perform an operation (+,-,*,x,/) on them and displays the result of that operation. The program should tell the user whether the result is an even number or odd number. If the result is an even number the program should generate again two integers and repeat the process again. The program will only stop when the result of the operation is an odd numberarrow_forwardOBJECT: Write a program to define two integer variables and assign values to them (you can use any values you like). Then do the following: 1.Compute and print their sum with an appropriate message. 2.Compute and print their product with an appropriate message. 3. Add their sum to their product and print the result with an appropriate message. 4.
