Answer:
The right answer is option 4: 2
Explanation:
Lists are used in Python to store elements of same or different data types.
Different functions are used in Python on List. One of them is count.
Count is used to count how many times a specific value occurs in a list.
The syntax for count is:
listname.count(value)
In the given code,
The output will be 2
Hence,
The right answer is option 4: 2

The divBySum method is intended to return the sum of all the elements in the int array parameter arr that are divisible by the int parameter num. Consider the following examples, in which the array arrcontains {4, 1, 3, 6, 2, 9}.
The call divBySum(arr, 3) will return 18, which is the sum of 3, 6, and 9, since those are the only integers in arr that are divisible by 3.
The call divBySum(arr, 5) will return 0, since none of the integers in arr are divisible by 5.
Complete the divBySum method using an enhanced for loop. Assume that arr is properly declared and initialized. The method must use an enhanced for loop to earn full credit.
/** Returns the sum of all integers in arr that are divisible by num
* Precondition: num > 0
*/
public static int divBySum(int[] arr, int num)
Answer:
The complete method is as follows:
public static int divBySum(int[] arr, int num){
int sum = 0;
for(int i:arr){
if(i%num == 0)
sum+=i;
}
return sum;
}
Explanation:
As instructed, the program assumes that arr has been declared and initialized. So, this solution only completes the divBySum method (the main method is not included)
This line defines the method
public static int divBySum(int[] arr, int num){
This line declares and initializes sum to 0
int sum = 0;
This uses for each to iterate through the array elements
for(int i:arr){
This checks if an array element is divisible by num (the second parameter)
if(i%num == 0)
If yes, sum is updated
sum+=i;
}
This returns the calculated sum
return sum;
}
/* missing precondition */
public String getChar(String str, int n) {
return str.substring(n, n 1); }
Write down the most appropriate precondition for the method so that it does not throw an exception.
Answer:
An appropriate precondition is:
0 <= n && n <= str.length() - 1
Explanation:
Required:
Write down an appropriate pre-condition for the program
From the question, we understand that the method accepts two parameters:
str -> A string value
n -> An integer value which represents the index of character to return from the string str
It should be noted that:
n must be within the range of 0 and str.length()-1
Take for instance:
str = "ABCDE";
n must be within the range 0 to 4 (inclusive) in order not to raise an exception. This is so because the string index starts at 0 and stops at 1 less than the length of the string.
Hence, the precondition can be written as:
0 <= n && n <= str.length() - 1
Which means: n = 0 to length - 1

The measure of software complexity that measure how complex a software is in machine's viewpoint in terms of how the size of the input data affects an algorithm's usage of computational resources is known as Computational Complexity.
a. True
b. False
Answer:
a. True
Explanation:
In Computer science, an algorithm can be defined as a standard formula or procedure which comprises of set of finite steps or instructions for solving a problem on a computer.
Basically, the time complexity of an algorithm is defined by f(n) if; for all "n" and all inputs with length "n" the execution of the algorithm takes a maximum of f(n) steps. Therefore, this is a measure of the efficiency of an algorithm.
Hence, the time complexity is a measure of the amount of time required by an algorithm to run till its completion of the task with respect to the length of the inpu
Computational complexity can be defined as a measure of software complexity that measure how complex a software is in machine's viewpoint in terms of how the size of the input data affects an algorithm's usage of computational resources such as memory or running time.

1.16 LAB: Input and formatted output: House real estate summary Sites like Zillow get input about house prices from a database and provide nice summaries for readers. Write a program with two inputs, current price and last month's price (both integers). Then, output a summary listing the price, the change since last month, and the estimated monthly mortgage computed as (currentPrice * 0.051) / 12 (Note: Output directly. Do not store in a variable.).
Ex: If the input is:
200000 210000
the output is:
This house is $200000. The change is $-10000 since last month.
The estimated monthly mortgage is $850.0.
Note: Getting the precise spacing, punctuation, and newlines exactly right is a key point of this assignment. Such precision is an important part of programming.
import java.util.Scanner;
public class LabProgram {
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
int currentPrice;
int lastMonthsPrice;
currentPrice = scnr.nextInt();
lastMonthsPrice = scnr.nextInt();
/* Type your code here. */
}
Answer:
Please find the complete code and the output in the attachement.
Explanation:
In the code, a class "LabProgram" is defined, and inside the main method two integer variable "currentPrice and lastMonthsPrice" is defined that uses the scanner class object is used for a user input value, and in the next step, two print method is declared that print the calculate of the integer variable.
The program is an illustration of output formats in Java
The statements that complete the program are:
System.out.printf("This house is $%d. The change is $%d since last month.\n",currentPrice,(currentPrice - lastMonthsPrice));System.out.printf("The estimated monthly mortgage is $%.1f.\n",(currentPrice * 0.051)/12);To format outputs in Java programming language, we make use of the printf statement, followed by the string literal that formats the required output
Take for instance:
To output a float value to 2 decimal place, we make use of the literal "%.2f"

Explanation:
Write the command and explain about each formula in MS Excel
1. SUM
2. AVERAGE
3. MAx
4. MIN
5. COUNT
Answer:
1. SUM --- The SUM function is used to sum all the values that are in a given range. Thus, for example, if you want to add the values between cells A1 and A3, you must write the following command: =SUM(A1:A10)
2. AVERAGE --- The AVERAGE function allows you to average a range of values, throwing the average of these values in the cell where the function is typed. For example, if you want to average the values included between B1 and B3, you should write the following function: =AVERAGE (B1: B3).
3. MAX --- The MAX function, for its part, returns the maximum value of the values included in the function. For example, if the maximum value included between the values C1 and C3 is known, the following function must be written: =MAX (C1: C3).
4. MIN --- The MIN function, in turn, allows to identify the minimum value of the range of values included in the function. For example, if the minimum value included between the values D1 and D3 is known, the following function must be written: =MIN (D1: D3).
5. COUNT --- The COUNT function, finally, is used to count all the cells that have numbers, which have been included in the range of the function. For example, if you want to count all cells that contain numbers between the values E1 and E3, you must write the following function: =COUNT (E1: E3).

compare and contrast Charles bebbage and Blaise Pascal inventions
Explanation:
A computer might be described with deceptive simplicity as “an apparatus that performs routine calculations automatically.” Such a definition would owe its deceptiveness to a naive and narrow view of calculation as a strictly mathematical process. In fact, calculation underlies many activities that are not normally thought of as mathematical. Walking across a room, for instance, requires many complex, albeit subconscious, calculations. Computers, too, have proved capable of solving a vast array of problems, from balancing a checkbook to even—in the form of guidance systems for robots—walking across a room.
Before the true power of computing could be realized, therefore, the naive view of calculation had to be overcome. The inventors who laboured to bring the computer into the world had to learn that the thing they were inventing was not just a number cruncher, not merely a calculator. For example, they had to learn that it was not necessary to invent a new computer for every new calculation and that a computer could be designed to solve numerous problems, even problems not yet imagined when the computer was built. They also had to learn how to tell such a general problem-solving computer what problem to solve. In other words, they had to invent programming.
They had to solve all the heady problems of developing such a device, of implementing the design, of actually building the thing. The history of the solving of these problems is the history of the computer. That history is covered in this section, and links are provided to entries on many of the individuals and companies mentioned. In addition, see the articles computer science and supercomputer.
Early history
Computer precursors
The abacus
The earliest known calculating device is probably the abacus. It dates back at least to 1100 BCE and is still in use today, particularly in Asia. Now, as then, it typically consists of a rectangular frame with thin parallel rods strung with beads. Long before any systematic positional notation was adopted for the writing of numbers, the abacus assigned different units, or weights, to each rod. This scheme allowed a wide range of numbers to be represented by just a few beads and, together with the invention of zero in India, may have inspired the invention of the Hindu-Arabic number system. In any case, abacus beads can be readily manipulated to perform the common arithmetical operations—addition, subtraction, multiplication, and division—that are useful for commercial transactions and in bookkeeping.
The abacus is a digital device; that is, it represents values discretely. A bead is either in one predefined position or another, representing unambiguously, say, one or zero.
Analog calculators: from Napier’s logarithms to the slide rule
Calculating devices took a different turn when John Napier, a Scottish mathematician, published his discovery of logarithms in 1614. As any person can attest, adding two 10-digit numbers is much simpler than multiplying them together, and the transformation of a multiplication problem into an addition problem is exactly what logarithms enable. This simplification is possible because of the following logarithmic property: the logarithm of the product of two numbers is equal to the sum of the logarithms of the numbers. By 1624, tables with 14 significant digits were available for the logarithms of numbers from 1 to 20,000, and scientists quickly adopted the new labour-saving tool for tedious astronomical calculations.
Most significant for the development of computing, the transformation of multiplication into addition greatly simplified the possibility of mechanization. Analog calculating devices based on Napier’s logarithms—representing digital values with analogous physical lengths—soon appeared. In 1620 Edmund Gunter, the English mathematician who coined the terms cosine and cotangent, built a device for performing navigational calculations: the Gunter scale, or, as navigators simply called it, the gunter. About 1632 an English clergyman and mathematician named William Oughtred built the first slide rule, drawing on Napier’s ideas. That first slide rule was circular, but Oughtred also built the first rectangular one in 1633. The analog devices of Gunter and Oughtred had various advantages and disadvantages compared with digital devices such as the abacus. What is important is that the consequences of these design decisions were being tested in the real world.
Digital calculators: from the Calculating Clock to the Arithmometer

Consider the following method, inCommon, which takes two Integer ArrayList parameters. The method returns true if the same integer value appears in both lists at least one time, and false otherwise.
public static boolean inCommon(ArrayList a, ArrayList b)
{
for (int i = 0; i < a.size(); i++)
{
for (int j = 0; j < b.size(); j++) // Line 5
{
if (a.get(i).equals(b.get(j)))
{
return true;
}
}
}
return false;
}
Which of the following best explains the impact to the inCommon method when line 5 is replaced by for (int j = b.size() - 1; j > 0; j--) ?
A. The change has no impact on the behavior of the method.
B. After the change, the method will never check the first element in list b.
C. After the change, the method will never check the last element in list b.
D. After the change, the method will never check the first and the last elements in list b.
E. The change will cause the method to throw an IndexOutOfBounds exception.
Answer:
The answer is "Option b".
Explanation:
In the given code, a static method "inCommon" is declared, that accepts two array lists in its parameter, and inside the method two for loop is used, in which a conditional statement used, that checks element of array list a is equal to the element of array list b. If the condition is true it will return the value true, and if the condition is not true, it will return a false value. In this, the second loop is not used because j>0 so will never check the element of the first element.

Answer:
Explanation:
The following code is written in Python. It is a function called guessMyNumber and like requested creates a random number and saves it to secretNumber. Then it continuously asks the user for their guess and compares it to the secret number. If the guess is correct it exits the loop otherwise it will continue to ask for a new guess.
import random
def guessMyNumber():
secretNumber = random.randint(1, 10)
print(secretNumber)
while True:
guess = input("Enter your guess: ")
guess = int(guess)
if (guess == secretNumber):
print("Congratulations you guessed correctly")
