x = int(input(second_int))

usernum = usernum // x

print(usernum, end= ' ')

usernum = usernum // x

print(usernum, end= ' ')

A hard disk has four surfaces (that's top and bottom of two platters). Each track has 2,048 sectors and there are 131,072 (217)
marysya [2.9K]

Answer:

128 GB

Explanation:

Here, we are interested in calculating the total capacity of the disk.

From the question, we can identify the following;

Number of surfaces = 4

Tracks per surface = 131,072

Number of sectors = 2,048

Each Block size = 512 bytes

Mathematically;

Total data capacity of the disk = no of tracks * no of sectors * block size

= 131,072 * 2048 * 512 bytes

= 2^17 * 2^11 * 2^9 bytes = 2^37 bytes

1 GB = 2^30 bytes

So 2^37 = 2^7 * 2^30

= 128 GB

nydimaria [60]

Answer:

  1. import java.util.Scanner;  
  2. public class Main {
  3.    public static void main(String[] args) {
  4.        Scanner input = new Scanner(System.in);
  5.        System.out.print("Please enter two characters: ");
  6.        String inputStr = input.nextLine();
  7.        if(inputStr.charAt(0) == 'B' || inputStr.charAt(0) == 'b'){
  8.            System.out.println("Biology");
  9.        }
  10.        else if(inputStr.charAt(0) == 'C' || inputStr.charAt(0)== 'c'){
  11.            System.out.println("Computer Science");
  12.        }
  13.        else if(inputStr.charAt(0) == 'I' || inputStr.charAt(0) == 'i')
  14.        {
  15.            System.out.println("Information Technology and Systems");
  16.        }
  17.        else{
  18.            System.out.println("Invalid major");
  19.        }
  20.        int num = Character.getNumericValue(inputStr.charAt(1));
  21.        if(num >= 1 && num <= 4){
  22.            switch (num){
  23.                case 1:
  24.                    System.out.println("freshman");
  25.                    break;
  26.                case 2:
  27.                    System.out.println("sophomore");
  28.                    break;
  29.                case 3:
  30.                    System.out.println("junior");
  31.                    break;
  32.                case 4:
  33.                    System.out.println("senior");
  34.                    break;
  35.            }
  36.        }
  37.        else{
  38.            System.out.println("Invalid year status");
  39.        }
  40.    }
  41. }

Explanation:

The code consists of two main parts. The part 1 is to validate the input major and print out the major according to the input character (Line 10 -22). If the input character is not matched with the target letters, a message invalid major will be displayed.

The part 2 is to validate the year status to make sure it only fall within the range of 1-4  (Line 26 -45). If within the range, the program will display the year major accordingly. If not a message invalid year status will be displayed.

What is the big-O performance estimate of the following function?
larisa [96]

Answer:

The time complexity of the code is O(log₇n).

Explanation:

The i is updated by 7*i.On each iteration i is multiplied by 7.So on finding the time complexity of the code given above it will come out to  be log base 7.

When we divide the input by 2 the time complexity is log base 2.

So on dividing it by 7 we get the time complexity of log base 7.
