Color Mixer
The colors red, blue, and yellow are known as primary colors because they cannot be made by mixing other colors. When you mix two primary colors, you get a secondary color, as shown here:
When you mix red and blue, you get purple.
When you mix red and yellow, you get orange.
When you mix blue and yellow, you get green.

- (Apartment problem) A real estate office handles , say, 50 apartment units. When the rent is, say, $600 per month, all the units are occupied. However, for each, say $40 increase in rent, one unit becomes vacant. Moreover, each occupied unit requires an average of $27 per month for maintenance. How many units should be rented to maximize the profit? Write a program that prompts the user to enter: The total number of units. The rent to occupy all the units. The increase in rent that results in a vacant unit. Amount to maintain rented unit. The program then outputs the number of units to be rented to maximize the profit.arrow_forwardcircles) Write a program that prompts the user to enter the center coordinates and radii of two circles and determines whether the second circle is inside the first or overlaps with the first, as shown in Figure 4.11. (Hint: circle2 is inside circle1 if the distance between the two centers <= | r1 - r2| and circle2 overlaps circle1 if the distance between the two centers <= r1 + r2.arrow_forwardWidgets and Gizmos An online retailer sells two products: widgets and gizmos. Each widget weighs 75 grams. Each gizmo weighs 112 grams. Write a program that reads the number of widgets and the number of gizmos in an order from the user. Then your program should compute and display the total weight of the order.arrow_forward
- Q1: (Palindrome number) Write a program that prompts the user to enter a three-digit integer and determines whether it is a palindrome number. A number is palindrome if it reads the same from right to left and from left to right. Here is a sample run of this program: Enter a three-digit integer: 121 121 is a palindrome Enter a three-digit integer: 123 123 not a palindromearrow_forwardQuestioin: Hidden Secret Problem! In this problem, you are given two names, you have to find whether one name is hidden into another. The restrictions are: You can change some uppercase letters to lower case and vice versa. You can add/remove spaces freely. You can permute the letters. And if both the names match exactly, then you can say that one name is hidden into another. Input Input starts with an integer T (≤ 100), denoting the number of test cases. Each case starts with two lines. Each line contains a name consists of upper/lower case English letters and spaces. You can assume that the length of any name is between 1 and 100(inclusive). Output For each case, print the case number and Yes if one name is hidden into another. Otherwise print No. Sample Input Output 3 Tom Marvolo Riddle I am Lord Voldemort I am not Harry Potter Hi Pretty Roar to man Harry and Voldemort Tom and Jerry and Harry Case 1: Yes Case 2: Yes Case 3: No And I want…arrow_forwardPython Coding (on PyCharm Community Edition) WHAT COLOUR SQUARE PART 1 - Positions on a chess board are identified by a letter and number combination. See diagram. The letter refers to the column and the number refers to the row : ** MUST USE IF / ELIF / ELSE or some version of it for full marks. Do not use multiple IF statements unless you are nesting *** Write a program that reads the position (row and column) and tells the user which colour it will be. Do this twice. For example, if the user enters g3 - it should tell you BLACK. You can use the modulus for this question or lists - we have done similar work in this course. Create a mathematical formula to work out the position and colour. * The user should be able to input EITHER upper or lowercase.arrow_forward
- (Geometry: great circle distance) The great circle distance is the distance between two points on the surface of a sphere. Let (x1, y1) and (x2, y2) be the geographi- cal latitude and longitude of two points. The great circle distance between the two points can be computed using the following formula: d = radius * arccos(sin(x1) * sin(x2) + cos(x1) * cos(x2) * cos(y1 - y2)) Write a program that prompts the user to enter the latitude and longitude of two points on the earth in degrees and displays its great circle distance. The average earth radius is 6,378.1 km. The latitude and longitude degrees in the formula are for north and west. Use negative to indicate south and east degrees.arrow_forward(Science: calculating energy) Write a program that calculates the energy needed to heat water from an initial temperature to a final temperature. Your program should prompt the user to enter the amount of water in kilograms and the initial and final temperatures of the water. The formula to compute the energy is Q = M * (finalTemperature – initialTemperature) * 4184 where M is the weight of water in kilograms, temperatures are in degrees Celsius, and energy Q is measured in joules.arrow_forwardProblem: Feed Nibble Monster Till Full Write a program that generates a number in [0, 500] at the beginning -- this corresponds to how hungry the monster is -- and keeps asking the user to feed the monster until that number falls to zero. Each time the user feeds the monster a nibble, hunger decreases by the decimal value of the character (i.e. if the user feeds 'A' hunger decreases by 65). But when the user feeds the monster some character that isn't a nibble, the hunger increases by the decimal value of the character (since puking depletes energy). Use while loop. Sample runs: Notice the loop exits after one iteration, because hunger was very low and one nibble made the monster full: Notice hunger increasing after non-nibble (pink highlight): Notice that the program just keeps going when the user feeds the monster only non-nibbles. Do you think the program will keep running forever if the user never gives the monster nibbles?arrow_forward
- Dice game Rules of the game: The players roll three dice, and the program adds the sides that turn up. After the first roll of the three dice, a player may choose to roll the dice as many times as they wish until the player gets at least one side 2 from a dice. When a player gets at least one side 2 from the dice, that player's score drops to zero, and the turn switches to the other player. Both players play the game for an equal number of turns, and the player who gets a score higher than 18 wins. If both players get a score higher than 18 within an equal number of turns, the player with the higher score wins. If both of the players got the same scores, print the scores of the players. These are the minimum required functions for this program. Design and implement these functions. You can create more functions if you choose to. Here is the provided starter code: # A program to play a Dice game. import random def roll_die(): ''' Simulate a die roll ''' def…arrow_forwardYou must use switch statements instead of if-else statements. If-else statements will not be accepted for this problem. You want to learn to play an instrument, but you need to know how much it's going to cost to buy it. The music store has the following table on their website: Write a menu-driven program that asks the user to input an instrument category and then an instrument. The program should give the user the price. The user should input an integer in the range of the choices you give them (for example, a user cannot input 3 if you only have 2 choices) and in response should be prompted to for the next set of choices. Once they make the final selection, the total should be printed to them as an integer with proper formatting as shown in the sample run. Sample run: Select a category: (1)Brass (2)Woodwind (3)Percussion 2 Select an instrument: (1)Flute (2)Saxophone 2 Your instrument will be $425. Ensure you are doing input validation, output Please enter a valid input. if the user…arrow_forward(Turtle: draw the Olympic symbol) Write a program that prompts the user to enter the radius of the rings and draws an Olympic symbol of five rings of the same size with the colors blue, black, red, yellow, and green, as shown in Figure 3.5carrow_forward
