a.Write a Python function sum_1k(M) that returns the sum푠푠= ∑1푘푘푀푀푘푘=1b.Compute s for M = 3 by hand and write
stealth61 [152]

Answer:

def sum_1k(M):

   s = 0

   for k in range(1, M+1):

       s = s + 1.0/k

   return s

def test_sum_1k():

   expected_value = 1.0+1.0/2+1.0/3

   computed_value = sum_1k(3)

   if expected_value == computed_value:

       print("Test is successful")

   else:

       print("Test is NOT successful")

test_sum_1k()

Explanation:

It seems the hidden part is a summation (sigma) notation that goes from 1 to M with 1/k.

- Inside the <em>sum_1k(M)</em>, iterate from 1 to M and calculate-return the sum of the expression.

- Inside the <em>test_sum_1k(),</em> calculate the <em>expected_value,</em> refers to the value that is calculated by hand and <em>computed_value,</em> refers to the value that is the result of the <em>sum_1k(3). </em>Then, compare the values and print the appropriate message

- Call the <em>test_sum_1k()</em> to see the result

Answer:

import java.util.Scanner;

public class LabProgram {

   public static void main(String[] args) {

       Scanner scnr = new Scanner(System.in);

       int inputYear;

       boolean isLeapYear;

       isLeapYear = false;

       inputYear = scnr.nextInt();

       // If a year is divisible by 400,  then it is a leap year

       if (inputYear % 400 == 0)

           isLeapYear = true;

       // If a year is divisible by 100,  then it is not a leap year

       if (inputYear % 100 == 0)

           isLeapYear = false;

       // If a year is divisible by 4,  then it is a leap year

       if (inputYear % 4 == 0)

           isLeapYear = true;

       if(isLeapYear)

           System.out.println(inputYear + " is a leap year.");

       else

           System.out.println(inputYear + " is not a leap year.");

   }

}

Explanation:

If a year is divisible by 400,  then set the boolean isLeapYear to true. If a year is divisible by 100,  then set the boolean isLeapYear to false. If a year is divisible by 4,  then set the boolean isLeapYear to true.

Check if isLeapYear is true, then print that it is a leap year. Otherwise, print that it is not a leap year.

Output:

1712

1712 is a leap year.
