DPI (Dots per inch), which is the resolution/detail that the printer can print.

Paper size, as you may want to print on a large range of media

Paper type, as conventional printers would print on standard paper, whilst different uses, such as photography, would benefit from printing on higher quality photo paper.

Connectivity, this can range from wireless over WiFi or Bluetooth, wired over Ethernet or USB, or even where you may have to connect a USB/SD card directly into the printer. All of these data transmission solutions would result in their own constraints and benefits.

baherus [9]

Answer:

The answer to this question can be given as:

Statement:

number = int(line.strip())

Explanation:

In the above statement, we declare an integer variable number accept the integer value from the file that name is line. In this line, we use the strip() function. This function returns a duplicate string with both starting and tracking characters removed (based on the string parameter passed). The strip() function removes characters from both sides (left and right) based on the parameter(a string defining the collection of characters to be removed).

You have a web application hosted in AWS cloud where the application logs are sent to Amazon CloudWatch. Lately, the web applica
zhenek [66]

Answer/Explanation:

In this scenario, you can:

- look at the existing CloudWatch logs for keywords related to the application error to create a custom metric;

- create a CloudWatch alarm for that custom metric which invokes an action to restart the EC2 instance;

- create alarms that automatically stop, terminate, reboot, or recover your EC2 instances using Amazon CloudWatch alarm actions;

- use the stop or terminate actions to help you save money when you no longer need an instance to be running; and

- use the reboot and recover actions to automatically reboot those instances or recover them onto new hardware if a system impairment occurs.

Write a program to find and print the sum of the first n cubes in the following four ways.
klio [65]

Answer:

The solution code is written in Java.

  1. public class Main {
  2.    public static void main(String[] args) {
  3.           System.out.print("Please enter a number: ");
  4.           Scanner console = new Scanner(System.in);
  5.           int n = console.nextInt();
  6.           calculateSum1(n);
  7.           calculateSum2(n);
  8.           calculateSum3(n);
  9.           calculateSum4(n);
  10.    }
  11.    public static void calculateSum1 (int num){
  12.        int sum1 = 0;
  13.        for(int i=1; i <= num; i++){
  14.            sum1 += i*i*i;
  15.        }
  16.        System.out.println("Sum 1 : " + sum1);
  17.    }
  18.    public static void calculateSum2 (int num){
  19.        int sum2 = num * num * (num + 1) * (num + 1) / 4;
  20.        System.out.println("Sum 2 : " + sum2);
  21.    }
  22.    public static void calculateSum3 (int num){
  23.        int sum3 = 0;
  24.        for(int i=1; i <=num; i++){
  25.            sum3 += i;
  26.        }
  27.        sum3 = sum3 * sum3;
  28.        System.out.println("Sum 3 : " + sum3);
  29.    }
  30.    public static void calculateSum4 (int num){
  31.        int sum4 = (num * (num + 1) * (2*num + 1)) / (4+2);
  32.        System.out.println("Sum 4 : " + sum4);
  33.    }
  34. }

Explanation:

Firstly we create four different methods that calculate the sum of the first n cubes in different ways (Line 13 - 43).

This is important to understand the concept of  operator precedence to work out the different ways of summation.

For example, The operator * and / will always have higher precedence than +.

On another hand, any expression enclosed within the parenthesis will have highest precedence and therefore the value will be evaluated prior to others.  

This is also important to understand the expression evaluation will always start from left to right.
