Week 1 : Programming Assignment 3

Consider First n even numbers starting from zero(0).Complete the code segment to calculate sum of all the numbers divisible by 3 from 0 to n. Print the sum.

Example:

Input: n = 5

-------
0 2 4 6 8
Even number divisible by 3:0 6
sum:6

import java.util.Scanner;
public class Exercise1_3 {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
int n=sc.nextInt();
int sum=0;
          **for (int i = 0; i < (n*2)-1; i++)

           System.out.print(sum);**
   }
}

Week 1 : Programming Assignment 4

Complete the code segment to check whether the number is an Armstrong number or not.

Armstrong Number:

A positive number is called an Armstrong number if it is equal to the sum of cubes of its digits for example 153 = 13+53+33, 370, 371, 407, etc.

import java.util.Scanner;

public class Exercise1_4 {

public static void main(String[] args) {

Scanner sc = new Scanner(System.in);

int n=sc.nextInt();

int result=0;

//Use while loop check the number is Armstrong or not.

//store the output(1 or 0) in result variable.

       int temp, digits=0, last=0, sum=0;
       temp=n;
       while(temp>0)
       {
           temp = temp/10;
           digits++;
       }
       temp = n;
       while (temp>0)
       {
           last = temp % 10;
           sum += (Math.pow(last, digits));
           temp = temp/10;
       }
       if(n==sum)
       {
           result = 1;
       }
       else
       {
               result = 0;
       }
           System.out.print(result);

}

Week 1 : Programming Assignment 5

Complete the code segment to help Ragav , find the highest mark and average mark secured by him in "s" number of subjects.

import java.util.Scanner;
public class Exercise1_5{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
double mark_avg;
int result;
int i;
int s;
//define size of array
s = input.nextInt();
//The array is defined "arr" and inserted marks into it.
int[] arr = new int[s];
for(i=0;i<arr.length;i++)
{
arr[i]=input.nextInt();
}

int sum = arr[0]; result = arr[0]; for (i=1; i<s; i++) { if (result < arr[i]) { result = arr[i]; } sum = sum + arr[i]; } mark_avg = sum / s; System.out.println(result); System.out.print(mark_avg);
}
}

All questions carry equal weightage. All Python code is assumed to be executed using Python3. You may submit as many times as you like within the deadline. Your final submission will be graded.

Note:

If the question asks about a value of type string, remember to enclose your answer in single or double quotes.
If the question asks about a value of type list, remember to enclose your answer in square brackets and use commas to separate list items.

1. What does h(27993) return for the following function definition?

def h(x):
    (d,n) = (1,0)
    while d <= x:
        (d,n) = (d*3,n+1)
    return(n)

Ans: 10
