Greatest Common Divisor Two integers A and B have the greatest common divisor which is the largest positive integer that divides A and B, evenly, without a remainder. One way to find the Greatest Common Divisor is to consider the prime factors for A = 372 and B = 84 as shown below. 372 223 * 31 84 22*3*7 GCD (372,84) = 2²*3= 12 In a well-documented Python program, hmwk3Q3.py, query the user for two integers. Use a while-loop to find the remainder R when dividing A by B.Replace the value of A with the value of B and replace the value of B with the value of R.Continue this process within the while-loop until the value of B is zero. At that time the value of A will be the GCD. In a comment, provide the response to your program when A= 98,025,733,547 and B = 2,345,109,894,323.

Ex. 8.4) The following functions are all intended to check whether a string contains any lowercase letters, but at least some of them are wrong. For each function, describe what the function actually does (assuming that the parameter is a string).
Create a function that determines whether each seat can "see" the front-stage. A number can "see" the front-stage if it is strictly greater than the number before it. Everyone can see the front-stage in the example below: # FRONT STAGE [[1, 2, 3, 2, 1, 1], [2, 4, 4, 3, 2, 2], [5, 5, 5, 5, 4, 4], [6, 6, 7, 6, 5, 5]] # Starting from the left, the 6 > 5 > 2 > 1, so all numbe # 6 > 5 > 4 > 2 - so all numbers can see, etc. Not everyone can see the front-stage in the example below: # FRONT STAGE [[1, 2, 3, 2, 1, 1], [2, 4, 4, 3, 2, 2], [5, 5, 5, 10, 4, 4], [6, 6, 7, 6, 5, 5]] # The 10 is directly in front of the 6 and blocking its v
JavaScript: const d = 4let a = 1if (true) {let a = 4var b = 2if (a < 5) {var c = 1b = 5}}console.log(a + b + c) What is is the output and why? a) The output is 7 because a, b, c and d are globally scoped variables b) The output is 11 because a, b, and c are all globally scoped variables while d is a block scoped variable c) The output is 7 because b and c are globally scoped variables d) The output is 6 because a is a block scoped variable and b is a globally scoped variable

A year in the modern Gregorian Calendar consists of 365 days. In reality, the earth takes longer to rotate around the sun. To account for the difference in time, every 4 years, a leap year takes place. A leap year is when a year has 366 days: An extra day, February 29th. The requirements for a given year to be a leap year are: 1) The year must be divisible by 4 2) If the year is a century year (1700, 1800, etc.), the year must be evenly divisible by 400 Some example leap years are 1600, 1712, and 2016. Write a program that takes in a year and determines whether that year is a leap year. Ex: If the input is: 1712 the output is: 1712 is a leap year. Ex: If the input is: 1913 the output is: 1913 is not a leap year. Your program must define and call the following function. The function should return True if the input year is a leap year or False otherwise.def is_leap_year(user_year)
Create a function that determines whether a number is Oddish or Evenish. A number is Oddish if the sum of all of its digits is odd, and a number is Evenish if the sum of all of its digits is even. If a number is Oddish, return "Oddish". Otherwise, return "Evenish" For example, oddishOr Evenish (121) should return "Evenish", since 1 + 2 + 1 = 4. oddishorEvenish (41) should return "Oddish", since 4 + 1 = 5. Examples oddishOr Evenish (43) → "Oddish" // 4 + 3 = 7 // 7 % 2 = 1 oddishorEvenish (373) // 3 + 7 + 3 = 13 // 13 % 2 = 1 → "Oddish" oddishOr Evenish (4433) → "Evenish" // 4 + 4 + 3 + 3 = 14 // 14 % 2 = 0

Q4. Write a program that calculate the person's Body Mass Index (BMI). The BMI is often used to determine if a person is overweight, underweight for his/her height. BMI is calculated as: BMI = (weight * 703) / (height*height) Here weight is in pounds and height is in inches. The program should display the message: - "Optimal Weight" if BMI is 18.5–25 - "Under Weight" if BMI is 25
