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.

Answers

Answer 1

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.

Complete the getOdds method so it returns a new ArrayList of Integers containing all odd Integers from the parameter ArrayList vals in the order they originally appeared. The contents of vals should not change. For example if an ArrayList containing the Integers 2,5,8,6,7,3, 12 in that order is passed as a parameter to getOdds, it should return an ArrayList containing the Integers 5, 7,3 in that order. Write your getOdds method in the U7_L2_Activity Three class. Use the runner class to test your method but do not add a main method to your U7_L2_Activity Three.java file or your code will not be scored correctly.

Write a method named numUnique that accepts a sorted array of integers as a parameter and that returns the number of unique values in the array. The array is guaranteed to be in sorted order, which means that duplicates will be grouped together. For example, if a variable called list stores the following values: int[] list

Answers

Answer:

The method in Java is as follows:

public static int numUnique(int list[]) {  

int unique = 1;  

for (int i = 1; i < list.length; i++) {  

 int j = 0;  

 for (j = 0; j < i; j++) {

  if (list[i] == list[j])  

   break;  

 }

 if (i == j)  

  unique++;  

}  

return unique;  

}  

Explanation:

This line defines the numUnique method

public static int numUnique(int list[]) {

This initializes the number of unique elements to 1

int unique = 1;  

This iterates through the list

for (int i = 1; i < list.length; i++) {

The following iteration checks for unique items

 int j = 0;  

 for (j = 0; j < i; j++) {

  if (list[i] == list[j]) If current element is unique, break the iteration

   break;  

 }

 if (i == j)  

  unique++;  

}

This returns the number of unique items in the list

return unique;  

}  

Finish the program to compute how many gallons of paint are needed to cover the given square feet of walls. Assume 1 gallon can cover 350.0 square feet. So gallons = the square feet divided by 350.0. If the input is 250.0, the output should be:

0.714285714286

Answers

Answer:

gallons_paint = wall_area / 350.0

Explanation:

So gallons = the square feet divided by 350.0:

So gallons = gallons_paint

the square feet = wall_area

then divide by 350.0

the whole thing:

wall_area = float(input())

# Assign gallons_paint below

gallons_paint = wall_area / 350.0

print(gallons_paint)

The program to compute how many gallons of paints are needed to cover the given square feet's of walls is as follows:

def square_feet_to_gallons(area):

  gallons = area / 350

  return gallons

print(square_feet_to_gallons(250))

1 gallon covers 350 square feet.

Therefore, gallons = area / 350

The user inputs is the area in square feet. Then the output should be the number of gallons.

The code explanation python.

We declared a function named square_feet_to_gallons and the argument is area.

Then we declared a variable and assigned the mathematical operation area/350 to it.

Then we return the gallons.

Finally, we call the function with a print statement.

Adding a paper clip to the vertical stabilizer of your glider will have what effect on its Center of Gravity (CG)?
The CG would move toward the rear.
The CG would stay the same.
The CG would move toward the nose.
O The CG would move lower

Answers

Answer:

the CG would move toward the rear.

Explanation:

Adding a paper clip to the vertical stabilizer of your glider will, the CG would move toward the rear. The correct option is A.

What is center of gravity?

The place on an item where the force of gravity is thought to act is known as the center of gravity (CG).

The gravitational pull is thought to be focused at the point where an object weighs on average. Depending on the object's size, shape, and mass distribution, the center of gravity will be in one place or another.

The impact of adding a paper clip to your glider's vertical stabilizer is to shift the center of gravity (CG) to the back of the glider.

This is due to the fact that the paper clip adds weight to the glider's rear, moving the center of mass there and, as a result, the center of gravity.

Thus, the correct option is A.

Answers

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

In 1623 the German astronomer and mathematician Wilhelm Schickard built the first calculator. He described it in a letter to his friend the astronomer Johannes Kepler, and in 1624 . .
