python help Q1: Over or Under Define a procedure over-or-under which takes in a number x and a number y and returns the following: -1 if x is less than y 0 if x is equal to y 1 if x is greater than y *Hint: You can use cond (define (over-or-under x y) 'YOUR-CODE-HERE ) ;;; Tests (over-or-under 1 2) ; expect -1 (over-or-under 2 1) ; expect 1 (over-or-under 1 1) ; expect 0 Q2: Filter Write a procedure filter-lst, which takes a predicate f and a list lst, and returns a new list containing only elements of the list that satisfy the predicate. The output should contain the elements in the same order that they appeared in the original list.

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.

Leap years have 366 days (29 Any year that is divisible by 4 but not by 100 is a leap year. If a year is divisible by 400 then it is also a leap year. So in short any year that is divisible by 4 is a leap year, unless it is divisible by 100, in which case it must also be divisible by 400 for it to be a leap year. Example: 1996 and 2000 were leap years, but 1900 was not. days in February).
Given two integers, a and b, return true if a can be divided evenly by b. Return false otherwise. Examples divides Evenly (98, 7) true // 98/7 = 14 → divides Evenly (85, 4) false // 85/4 = 21.25 → Notes a will always be greater than or equal to b.

Homework 5 CMP 167: Programming Methods I Lehman College, City University of New York Homework 5-1 I Write a program with a loop that iterates as long as an int variable called num is less or equal to 50. Num must be initialized with a value of 1 and incremented by 1 with each iteration. Each iteration of the loop must print all appropriate sentences for that number according to the following 1. If num is odd, output: num is an odd number 2. If num is even, output: num is an even number output: num is divisible by 2 3. If num is divisible by 2, 4. If num is divisible by 5, output: num is divisible by 5 5. If num is divisible by 8, output: num is divisible by 8 6. If num is divisible by 11, output: num is divisible by 11 Please note that your class should be named FirstLoop.
