Another pitfall cited in Section 1.10 is expecting to improve the overall performance of a computer by improving only one aspect

of the computer. Consider a computer running a program that requires 250 s, with 70 s spent executing FP instructions, 85 s executed L/S instructions, and 40 s spent executing branch instructions. 1.13.2 [5] <1.10> By how much is the time for INT operations reduced if the total time is reduced by 20%?

Answer:

5.6\:\%

Explanation:

Given:

Let Floating Point to FP and the execution time of the FP = 70s

The total time of the CPU = 250s

Execution time of the Branch instruction = 40s

Execution time of the L/S instruction = 85s

Then, we have to decrease the FP instruction time.

            0.8 \times 70s = 56s

Then, we have to find the total time required to run the program.

             250-(70-56)=236s

Then,\: we\:decrease\:the\:total\:time=The\:total\:time\:of \:the\:CPU-\:total\:time

              250s\:-\:236s= 14s

Finally, the percentage of the decreased total time.

             (14s\setminus 250s)\times 100

                            =5.6\:\%

Write a function called which_vowels_present that takes a single string parameter. Complete the function to return a list of str
romanna [79]

Answer:

import java.util.ArrayList;

import java.util.List;

public class Vowels {

   public static void main(String[] args) {

   String word = "I am David from Nigeria";

       System.out.println(which_vowels_present(word));

   }

   public static List which_vowels_present(String enteredWord){

       List<Character>list = new ArrayList<>();

       String word = enteredWord.toLowerCase();

       for (int i =0; i<word.length(); i++){

           if (word.charAt(i) == 'a' || word.charAt(i) == 'e' || word.charAt(i) == 'i'

                   || word.charAt(i) == 'o' || word.charAt(i) == 'u') {

               list.add(word.charAt(i));

           }

       }

       return list;

   }

}

Explanation:

  • Using Java programming Language
  • Import java.util.ArrayList; and java.util.List
  • Create the method which_vowels_present which accepts a string parameter
  • Within the method create a list object
  • Use a for loop to iterate the string. within the for loop use an if statement to check individual characters of the string if any is a vowel, add it to the list
  • return the list
  • In the main method, create a test string, call the method and pass the string as parameter
