In cryptarithmetic puzzles, mathematical equations are written using letters. Each letter can be a digit from 0 to 9, but no two letters can be the same. Here is a sample problem:
A solution to the puzzle is
Write a
The simplest technique is to use a nested loop for each unique letter (in this case T, O, G, D). The loops would systematically assign the digits from

- A regular polygon is an n-sided polygon in which all sides are of the same length and all angles have the same degree (i.e., the polygon is both equilateral and equiangular). The formula for computing the area of a regular polygon is Area = ( n * s2 ) / (4 * tan( π/n) Here, s is the length of a side. Write a program that prompts the user to enter the number of sides and their length of a regular polygon and displays its area.arrow_forwardIn CORAL LANGUAGE please and thank you! 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 Hint: Find the smallest value, and then subtract it from all three values, thus removing the gray.arrow_forwardWrite a program that calculates the equivalent resistance of a circuit. n electrical resistors with resistance values R1, R2,.., Rn are said to be connected in parallel if the same voltage is applied across each. 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. Test your program with R1= 1 kn, R2= 2 kn, R3= 4 kQ and R4= 8 kQ.arrow_forward
- Python programming In a department store sale, customers who purchase over 2000 are given 10% discount. Write a program that will accept for the purchase amount of a customer, solve for his/her discount if there’s any, ask for the money he/she is going to pay, then output the discounted price and the change of the customer.”arrow_forwardWrite a program that picks four cards from a deck of 52 cards and computes their sum. An ace, king, queen, and jack represent 1, 13, 12, and 11, respectively. Your program should display the number of picks that yieldthe sum of 24.arrow_forwardThe body mass index, BMI, is a measure used to determine if a person is overweight or not. We can calculate BMI from the weight of the person (in pounds) and the height (in inches) of the person.The formula for calculating BMI is:BMI = (weightInPounds * 703) divided by (heightInInches squared)In this problem, you will develop a Java program as a BMI calculator, that reads the user’s weight in pounds and height in inches, then calculates and displays the user’s body mass index BMI. Also, display the following information {from the US Department of Health} so the user can evaluate his/her BMI:BMI values:Underweight: less than 18.5Normal: between 18.5 and 24.9Overweight: between 25 and 29.9Obese: 30 or greaterarrow_forward
- Coupon collector is a classic statistic problem with many practical applications. The problem is to pick objects from a set of objects repeatedly and determine how many picks are needed for all the objects to be picked at least once. A variation of the problem is to pick cards from a shuffled deck of 52 cards repeatedly and find out how many picks are needed before you see one of each suit. Assume a picked card is placed back in the deck before picking another. Write a program to simulate the number of picks needed to get four cards from each suit and display the four cards picked (it is possible that a card may be picked twice).arrow_forwardThis example creates a program to teach a first grade child how to learn subtractions. The program randomly generates two single- digit integers number1 and number2 with number1 > number2 and displays a question such as "What is 9 – 2?" to the student. After the student types the answer, the program displays a message to indicate whether the answer is correct.arrow_forwardA fish-finder is a device used by anglers to find fish in a lake. If the fish-finder finds a fish, it will sound an alarm. It uses depth readings to determine whether to sound an alarm. For our purposes, the fish-finder will decide that a fish is swimming past if:there are four consecutive depth readings which form a strictly increasing sequence (such as 3 4 7 9) (which we will call "Fish Rising"), orthere are four consecutive depth readings which form a strictly decreasing sequence (such as 9 6 5 2) (which we will call "Fish Diving"), orthere are four consecutive depth readings which are identical (which we will call "Constant Depth").All other readings will be considered random noise or debris, which we will call "No Fish."Create a Python program called "fishfinder_firstname_lastname" that takes 1 input of string of 4 numbers separated with comma. Your program must display "Fish Rising", "Fish Diving.", "Fish At Constant Depth" or "No Fish".Example:30,10,20,20 Must display No…arrow_forward
- in C# Sometimes figuring letter grades is hard. Write a program that asks for, and reads from the user, a midterm exam grade and a final exam grade. Compute the average of those two grades and ouput a letter grade based on the scale shown below. CHALLENGE PROBLEM: One of my graduate school classes modified the above calculation. This professor said that the final grade would be determined by the simple average of the midterm and the final, however, if the student scored better on the final than they did on the midterm, the professor would weight the midterm exam at 25%, and the final exam at 75% when computing the final grade. Modify your code to use this professors modification in determining letter grade. Here is the grading scale:arrow_forwardIN C PROGRAMMING LANGUAGE A resistor is a circuit device designed to have a specific resistance value between its ends. Resistance values are expressed in ohms (Ω) or kilo-ohms (kΩ). Resistors are frequently marked with colored bands that encode their resistance values, as shown in the Figure. The first two bands are digits, and the third is a power-of-ten multiplier. The Table below shows the meanings of each band color. For example, if the first band is green, the second is black, and the third is orange, the resistor has a value of 50 × 103 Ω or 50 k Ω. The information in the Table can be stored in a C program as an array of strings. char COLOR_CODES[10][7] = {"black", "brown", "red", "orange", "yellow", "green", "blue", "violet", "gray", "white"}; Notice that “red” is COLOR_CODES[2] and has a digit value of 2 and a multiplier value of 102. In general, COLOR_CODES[n] has digit value n and multiplier value 10n. Write a program that prompts for the colors…arrow_forwardA number is called pandigital if it uses all of the digits from 1 to n exactly once, where n is the number of digits in the number. So, for example, the five-digit number 15432 is pandigital, but the five-digit number 11132 is not. Again, the four-digit number 4123 is pandigital, but the four-digit number 8312 is not. Finally, the one-digit number 1 is pandigital, but the one-digit number 3 is not. You should use list comprehension in your solution. Fill out the function is_pandigital. Hint: Using the range function list out all the numbers that should be in a pandigital number of a given length and then check if each of those numbers appears in the number you're checking >>> is_pandigital(1) True >>> is_pandigital(2) False >>> is_pandigital(12) True >>> is_pandigital(15432) True >>> is_pandigital(11123) False def is_pandigital(num): Note: Python Programmingarrow_forward
