What is the value of each of these prefix expressions

BARSIC [14]

The value of the given prefix expression *2 / 8 4 3 is calculated to be; 1

<h3>How to work with preorder transversals?</h3>

We are given the expression; *2 / 8 4 3

We will start from the rightmost operation symbol.

For every operation symbol, the two integers following the operation symbol are the symbols on which the operation needs to be performed. Then we replace the operation symbol with the two following integers by the result of the operation.

Then we repeat for the rightmost operation symbol in the remaining string.

*2 / 8 4 3

8 / 4 = 2

⇒ *2 2 3

2 * 2 = 4

4 - 3 = 1

Thus the value of the prefix expression is then 1.

2.17 LAB: Word frequencies - methods Write a program that reads a list of words. Then, the program outputs those words and their

pickupchik [31]

Using the knowledge in computational language in JAVA it is possible to write a code that reads a list of words.

<h3>Writting the code in JAVA:</h3>

import java.util.*;

//class name LabClass

public class LabClass{

//function getFrequencyOfWord with array wordList, ListSize and currWord as parameter

public static int getFrequencyOfWord(String[] wordsList, int ListSize, String currWord){

int frequency = 0;

//for loop for iteration

for(int i=0; i<ListSize; i++){

//if current word matches with words present in list

//then increase the frequency by 1

if(wordsList[i].compareTo(currWord)==0){

frequency++;

}

//return frequency at last

return frequency;

}

//main function

public static void main(String[] args) {

//creating object of Scanner class

Scanner sc = new Scanner(System.in);

int size;

//asking user to input size of list

System.out.println("Enter the size of list :");

size = sc.nextInt();

//creating array of same size as user input size

String[] wordList = new String[size];

sc.nextLine();

//asking user to input array elements

System.out.println("Enter list elements one by one :");

for(int i =0; i<size; i++)

{

wordList[i] = sc.nextLine();

}

System.out.print("\n");

sc.close();

//calling function getFrequencyOfWord in every iteration by passing

//required arguments to it

for(int i=0; i<size; i++)

{

String currWord = wordList[i];

int count = getFrequencyOfWord(wordList, size, currWord);

//printing result

System.err.println(currWord + " : " + count);

}

}

What was the legacy Louis XIV left for his successor, Louis XV?

lidiya [134]

In the king's final hours, he received his five-year-old great-grandson, the successor future Louis XV, to share his legacy. He advised his grandson to try to avoid going to war as much as possible, and to focus on relieving the burden on the people. He said that this was the ruin of the people.

<h3>What does legacy mean?</h3>

A legacy is someone who has three mortal grandparents and one godly grandparent, or who is a further descendant of a particular deity. There is no distinction between a legacy of Ares/Mars and a legacy of Zeus/Jupiter because a legacy only counts the god it is descended from as an ancestor, not that deity's parents or grandparents. But through different ancestral combinations, it is possible to carry the genetic legacy of two or more gods.

As with Octavian's gift of prophecy or Periclymenus' descendants gaining the ability to change their shape, it is demonstrated that legacies can occasionally possess the skills of their divine ancestor. Some legacies do possess the skills of their divine ancestor, but this is only true of some of them.
