A filter is limited to extracting data from a single table. <br> a. True <br> b. False

oksano4ka [1.4K]

<span>It is true that a filter is limited to extracting data from a single table.

</span><span>Extraction is the operation of copying data from a database into a file or onto a network connection. This is the first step of the ETT process: data must be extracted from the source system(s) so that this data may be subsequently transformed and loaded into the data warehouse.</span>

A file named 'input.txt' contains a list of words. Write a program that reads the content of the file one word at a time. Check

Margarita [4]

Answer:

// here is code in java.

import java.io.*;

import java.util.Scanner;

class Main{

// function to check a word is palindrome or not

private static boolean is_Palind(String str1)

{

// if length of String is 0 or 1

if(str1.length() == 0 || str1.length() == 1)

{

return true;

}

else

{

// recursively check the word is palindrome or not

if(str1.charAt(0) == str1.charAt(str1.length()-1))

{

return is_Palind(str1.substring(1,str1.length()-1));

}

else

{

return false;

}

}

}

// driver function

public static void main(String[] args)

{// variable to store word

String word;

// BufferedWriter object

BufferedWriter buff_w = null;

// FileWriter object

FileWriter file_w = null;

// Scanner object

Scanner sc = null;

try

{

// read the input file name

sc = new Scanner(new File("input.txt"));

// output file

file_w = new FileWriter("output.txt");

// create a buffer in output file

buff_w = new BufferedWriter(file_w);

// read each word of input file

while(sc.hasNext())

{

word = sc.next();

// check word is palindrome or not

if(is_Palind(word))

{

// if word is palindrome then write it in the output file

buff_w.write(word);

buff_w.write("\n");

}

}

// close the buffer

buff_w.close();

// close the input file

sc.close();

}

// if there is any file missing

catch (FileNotFoundException e) {

System.out.println("not able to read file:");

}

// catch other Exception

catch (IOException e) {

e.printStackTrace();

}

}

}

Explanation:

Create a scanner class object to read the word from "input.txt" file.Read a word from input file and check if it is palindrome or not with the help of is_Palind() function.it will recursively check whether string is palindrome or not. If it is palindrome then it will written in the output.txt file with the help of BufferedWriter object. This will continue for all the word of input file.

Input.txt

hello world madam

level welcome

rotor redder

output.txt

madam

Write a program with total change amount in pennies as an integer input, and output the change using the fewest coins, one coin

Serjik [45]

Answer:

Here is the Python program:

def FewestCoinVals(): # function to output change using fewest coins

total_change = int(input('Enter change amount in pennies: '))

#prompts user to enter total change amount in pennies

if total_change <= 0: # if value of total_change is less or equal to 0

print('no change') # prints no change

else: # if value of total_change is greater than 0

dollars = total_change // 100

#calculate value of dollars by dividing total_change by 100

total_change %= 100 #take mod of value of total_change with 100

#calculate value of quarters by dividing total_change by 100

quarters = total_change // 25

total_change %= 25 #take mod of value of total_change with 25

#calculate value of dimes by dividing total_change by 100

dimes = total_change // 10

total_change %= 10 #take mod of value of total_change with 10

#calculate value of nickels by dividing total_change by 100

nickels = total_change // 5

total_change %= 5 #take mod of value of total_change with 5

pennies = total_change

#value of pennies is equal to value of total_change

#the if elif statement checks for the singular and plural coin names

if dollars >1:

print('dollars: ',dollars)

elif dollars ==1:

print('dollar: ',dollars)

if quarters > 1:

print('quarters: ',quarters)

elif quarters ==1:

print('quarter: ',quarters)

if dimes >1:

print('dimes: ',dimes)

elif dimes ==1:

print('dime: ',dimes)

if nickels >1:

print('nickels: ',nickels)

elif nickels ==1:

print('nickel: ',nickels)

if pennies >1:

print('pennies: ',pennies)

elif pennies ==1:

print('penny: ',pennies)

#calls the FewestCoinVals() function

FewestCoinVals()

Explanation:

The program prompts the user to enter change amount in pennies and has int() function to convert input value to integer. If the value entered is less than or equal to 0 it displays message "no change", otherwise it converts the value using fewest coins. The formulas for converting to each type is given in the code. It uses if and elif statements to check if the final value of total_change has singular or plural coin names such as penny or pennies. The program along with output is attached as the screen shot.
