Department of Computer Science & Engineering Practice 1 Heating and cooling degree-days are measures used by utility companies to estimate energy requirements. If the average temperature for a day is below 60, then the number of degrees below 60 is added to the heating degree-days. If the temperature is above 80, the amount over 80 is added to the cooling degree-days. Write a program that accepts a sequence of average daily temps and computes the running total of cooling and heating degree-days. The program should print these two totals after all the data has been processed. 컴퓨터의 개념 및 실습 Practice 2 The Syracuse sequence is generated by starting with a natural number and repeatedly applying the following function until reaching 1: 𝑥/2 , 𝑖𝑓 𝑥 𝑖𝑠 𝑒𝑣𝑒𝑛 𝑠𝑦𝑟 𝑥 = 3𝑥 + 1, 𝑖𝑓 𝑥 𝑖𝑠 𝑜𝑑𝑑 For example, the Syracuse sequence starting with 5 is: 5, 16, 8, 4, 2, 1. Write a program that gets a starting value from the user and then prints the Syracuse sequence for that starting value. 컴퓨터의 개념 및 실습 Practice 3 The Goldbach conjecture asserts that every even number is the sum of two prime numbers. Write a program that gets a number from the user, checks to make sure that it is even, and then finds two prime numbers that sum to the number. Hints: Take advantage of a function we developed in the last class to determine whether the input is a prime number or not. 컴퓨터의 개념 및 실습
