A common preprocessing step in many natural language processing tasks is text normalization, wherein words are converted to lowe

rcase, extraneous whitespace is removed, etc. Write a function normalize(text) that returns a normalized version of the input string, in which all words have been
converted to lowercase and are separated by a single space. No leading or trailing whitespace should be present in the output.

>>> normalize("This is an example.")
'this is an example.'
>>> normalize(" EXTRA SPACE ")
'extra space'

The section of the cpu that is responsible for performing mathematical operations.
nlexa [21]

The CPU executes arithmetic and logic operations in the arithmetic and logic unit (ALU).

<h3>What is an ALU, or an arithmetic and logic unit?</h3>
  • A combinational digital circuit known as an arithmetic logic unit computes arithmetic and bitwise operations on integer binary integers.
  • A floating-point unit, on the other hand, works with floating-point numbers.
  • The component of a central processing unit known as an arithmetic-logic unit performs arithmetic and logic operations on the operands in computer instruction words.
  • An Arithmetic Logic Unit (ALU) is a component found within computers that can execute logical operations in addition to arithmetic operations, such as AND, OR, Ex-OR, invert, etc (e.g. Addition, Subtraction, etc.).

4.2: Roman Numeral Converter Write a program that asks the user to enter a number within the range of 1 through 10. Use a switch
Reptile [31]

Answer:

The solution code is written in Java

  1. import java.util.Scanner;
  2. public class Main {
  3.    public static void main (String [] args) {
  4.        Scanner inStream = new Scanner(System.in);
  5.        System.out.print("Please input a number (1 - 10): ");
  6.        int num = inStream.nextInt();
  7.        if(num < 1 || num > 10){
  8.            System.out.println("The input must be between 1 - 10");
  9.        }else{
  10.            switch(num){
  11.                case 1:
  12.                    System.out.println("I");
  13.                    break;
  14.                case 2:
  15.                    System.out.println("II");
  16.                    break;
  17.                case 3:
  18.                    System.out.println("III");
  19.                    break;
  20.                case 4:
  21.                    System.out.println("IV");
  22.                    break;
  23.                case 5:
  24.                    System.out.println("V");
  25.                    break;
  26.                case 6:
  27.                    System.out.println("VI");
  28.                    break;
  29.                case 7:
  30.                    System.out.println("VII");
  31.                    break;
  32.                case 8:
  33.                    System.out.println("VIII");
  34.                    break;
  35.                case 9:
  36.                    System.out.println("IX");
  37.                    break;
  38.                case 10:
  39.                    System.out.println("X");
  40.                    break;
  41.            }
  42.        }
  43.    }
  44. }

Explanation:

The first part of this program (Line 6 - 8) is to get input number from user using Scanner object. Input validation has been done to check if the input number is in the acceptable range (Line 10). If not, an error message will be displayed (Line 11).

If the input number is in the range of 1 - 10, the number will go through a series of switch statements checking. If the number meet the condition in one of the switch cases, it will print the corresponding roman numeral specified in the case block (Line 13 - 44). For example, if input number is 9, the case 9 condition is met and "IX" will be printed.

What are Loop Errors? Describe briefly. What aresymptoms of Loop Errors?
victus00 [196]

Answer:

The errors in the loop condition such that it is not giving desired results or it is not running accordingly.There are different types of loop errors which are as following:-

1.Infinite loop:-When the is not able to stop then the error is called infinite loop. for ex:-

int i=1;

while(i!=0)

{

cout<<"I am King"<<endl;

i++;

}

2.Off by one error:-This error mostly happens in loop for arrays as indexing of the array is from 0 to size-1 .So looping over the array up to the size is a off by one error.

3.Equality v/s assignment operator error:-In this error the condition in the loop is like this d=f which is wrong since = is assignment operator it assigns the value of f to d while d==f checks that the value of d and f are equal or not.

4.&& v/s || loop error:- In this error we use and operator (&&) instead of or operator (||) and vice versa.

symptoms of loop errors are not the desired output.
