Each element in a dictionary has two parts: a key and a value. You use a key to locate a specific value.
a) True
b) False

Answers

Answer 1

Answer: TRUE

Explanation:

Elements in a dictionary are usually composed of two parts ; the key which could be viewed as the file name used to store the value. In general a dictionary written in the pattern; {key : value}. A certain value can be located, modified, deleted and added to a dictionary by using the dictionary key attached to each value in the dictionary object created. Each dictionary key should be unique and will be a string of letters which holds a particular value.

Give a recursive algorithm that takes as input two non-negative integers x and y and returns the sum of x and y. The only arithmetic operations your algorithm can perform are Increment(x) which returns x 1 and Decrement(x) which returns x-1. Your algorithm should have no loops.

Answers

Answer:

Following are the code to this question:

Cal_sum(x,y)//defining a recursive method Cal_sum that takes two variable as a parameter

{

if(x==0)// defining If that checks x equal to 0

return y; //return y value

x- 1;//decreasing x value  

y+1;//increasing y value

return Cal_sum(x,y)// calling method recursively

}

Explanation:

In the above-given code, a recursive method "Cal_sum" is declared, that accepts two-variable "x and y" in its parameter, and use if block to checks x is equal to 0 and return the value y variable, and, in the next step, it decreases the value of " x" by "1" and increment the value of y by "1", and call the method "Cal_sum" recursively.

The recursive program which calls itself in a function is used to return the value of y for a given x, y value in the program. The code written in python 3 goes thus :

def calc_sum (x,y) :

#initializes a function named calc_sum which takes in two arguments

if x ==0 :

#checks of the value of x is equal to 0

return y

#it returns y if x == 0

else :

#otherwise

x = x - 1

# decrease the value of x by 1

y = y + 1

#increase the value of y by 1

return calc_sum(x,y)

# calls the function recursively until x ==0

A sample run of the program is given below

print(calc_sum(4, 5 ))

Write a method getIntVal that will get the correct value input as integer numbers from the user. The input will be validated based on the first two numbers received as parameters.

Answers

Complete Question:

Write a method getIntVal that will get the correct value input as integer numbers from the user. The input will be validated based on the first two numbers received as parameters.

In other words, your program will keep asking for a new number until the number that the user inputs is within the range of the <firstParameter> and <secondParameter>.

The method should present a message asking for the value within the range as:

Please enter a number within the range of (<firstParameter> and <secondParameter>):

Note that <firstParameter> should be changed by the value received as that parameter and <secondParameter> as well.

If the user inputs a value that it is lower than the first value, the program will show the message:

The input number is lower than <firstParameter>

Note that <firstParameter> should be changed by the value received as that parameter

If the user inputs a value that it is greater than the first value, the program will show the message:

The input number is greater than <secondParameter>

Note that <secondParameter> should be changed by the value received as that parameter.

You do not need to modify anything in the main method, you just need to write the missing parts of your new getIntVal method.

Answer:

#include<iostream>

using namespace std;

void getIntVal(int num1, int num2) {

int num;

cout<<"Please enter a number within the range of "<<num1<<" and "<<num2<<": ";

cin>>num;

while(num<num1 || num>num2) {

if(num<num1) {

cout<<"The input number is lower than "<<num1<<endl;

}

if(num>num2) {

cout<<"The input number is greater than "<<num2<<endl;

}

cout<<"Please enter a number within the range of "<<num1<<" and "<<num2<<": ";

cin>>num;

}

cout<<"Output: "<<num;

}

int main() {

int num1,num2;

cout<<"Enter lower bound: ";

cin>>num1;

cout<<"Enter upper bound: ";

cin>>num2;

Write a method called printIndexed that accepts a String as itsparameter and prints the String's characters in order followed bytheir indexes in reverse order. For example, the call ofprintIndexed("ZELDA"); should print Z4E3L2D1A0 to the console.

Answers

Answer:

def printIndexed(s):

   for i in range(len(s)):

       print(s[i] + str(len(s) - 1 - i), end="")

       

   

printIndexed("ZELDA")

Explanation:

*The code is in Python.

Create a method named printIndexed that takes one parameter, s

Create a for loop that iterates the length of the s times

Inside the loop, print the characters from starting and indexes from the end

Note that in order the print the current character, you need to use indexing. s[i] refers to the current character of the string (the value of the i starts from 0 and goes until length of the s - 1). Also, to print the indexes from the end, you need to subtract the i from the length of the s - 1

For example, in the first iteration, i = 0:

s[i] = s[0] = Z

len(s) - 1 - i = 5 - 1 - 0 = 4

if opcode == "+":

    print(operand1 + operand2)

elif opcode == "-":

    print(operand1 - operand2)

elif opcode == "*":

    print(operand1 * operand2)

elif opcode == "/":

    print(operand1 / operand2)

else:

    print("Invalid Operator")

Explanation:

This prompts user for operator

opcode = input("Enter operator: +,-,*,/")

The next two lines prompt user for two operands

operand1 = float(input("Operand 1: "))

operand2 = float(input("Operand 2: "))

This performs + operation if operator is +

if opcode == "+":

    print(operand1 + operand2)

This performs - operation if operator is -

elif opcode == "-":

    print(operand1 - operand2)

This performs * operation if operator is *

elif opcode == "*":

    print(operand1 * operand2)

This performs / operation if operator is /

elif opcode == "/":

    print(operand1 / operand2)

This displays invailid operator if input operator is not +,-,* or /

Infrastructure as a Service (IaaS) replaces the _________ of the computer hierarchy with an Internet-based infrastructure.A. digital logic level through user levelsB. digital logic level through high-level language levelsC. system software level through high-level language levelsD. digital logic level through machine levels

Answers

Answer:

D. digital logic level through machine levels

Explanation:

In Computer science, the modern computer systems are basically organized in levels and this is known as computer hierarchy. The three levels in a chronological order are operating system level, machine language level and digital (hardware) logic level.

A digital logic level is the most fundamental level of a computer and can be defined as a level of the computer hierarchy which typically comprises of wires and gates. In digital circuits, the two (2) main logic level of the binary logic state are logical low and logical high which is typically denoted by the number 0 and 1 respectively.

In Computer science, the Infrastructure as a Service (IaaS) replaces the digital logic level through machine levels of the computer hierarchy with an Internet-based infrastructure. This is what enables various users to access resources that are available over the internet through the use of cloud storage.

Write a class named TestScores. The class constructor should accept an array of test scores as its argument. The class should have a method that returns the average of the test scores. If any test score in the array is negative or greater than 100, the class should throw an IllegalArgumentException. Demonstrate the class in a program.

Answers

import java.util.Arrays;

public class TestScores {

   public static float getAverage(float arr[]){

       float total = 0;

       for (float x : arr){

           if (x < 0 || x > 100){

               throw new IllegalArgumentException();

           }

           else{

               total += x;

           }

           

       }

       return (total / arr.length);

   }

   

   public static void main(String [] args){

       float arr[] = {1,100,0,43,-1};

       System.out.println(getAverage(arr));

   }

}

In the main method we test our getAverage method with the arr array. You can replace the values in the arr array and test your own values. I hope this helps!

The code example of the implementation of the TestScores class in Java is shown below:

What is the class?

java

import java.util.Arrays;

public class TestScores {

   private int[] scores;

   public TestScores(int[] scores) {

       this.scores = scores;

   }

   public double getAverage() {

       int sum = 0;

       for (int score : scores) {

           if (score < 0 || score > 100) {

               throw new IllegalArgumentException("Invalid test score: " + score);

           }

           sum += score;

       }

       return (double) sum / scores.length;

   }

   public static void main(String[] args) {

       int[] scores = {85, 90, 92, 88, 95};

       TestScores testScores = new TestScores(scores);

       try {

           double average = testScores.getAverage();

           System.out.println("Average test score: " + average);

       } catch (IllegalArgumentException e) {

           System.out.println("Error: " + e.getMessage());

       }

   }
