To implement a queue system without duplicates, you can use a set data structure to keep track of the elements already present in the queue.
When a new element is added to the queue, first check if it already exists in the set. If it does, discard the element and don't add it to the queue. If it doesn't, add it to both the queue and the set. This way, duplicates will not be allowed in the queue.
When removing an element from the queue, also remove it from the set to ensure that it can be added again in the future if needed.
Using a set data structure has a time complexity of O(1) for adding and checking elements, making it an efficient solution for preventing duplicates in a queue. Additionally, using a set instead of iterating through the queue to check for duplicates can also save time and improve performance.

The following are two different images that are encoded using the same algorithm. The images are each in a 5 by 5 grid of pixels where each pixel is black, white, red, green or blue.
The image on the left gets encoded and compressed down to 21 digits while the image on the right gets compressed down to 25 digits. Although the same algorithm was used to encode and compress these images, why are the end results a different length?
The algorithm was probably used improperly in the image on the right, causing it to be a longer length than it should have been.
Because this is a lossy compression, sometimes information is lost during the compression.
The amount of size reduction from compression depends on the amount of redundancy in the original data.
The image on the right uses more colored squares and therefore requires more digits to represent the pixels.
Answer: The amount of size reduction from compression depends on the amount of redundancy in the original data.
The reason why the end results have a different length is because: C. The amount of size reduction from compression depends on the amount of redundancy in the original data.
What is a lossy compression?A lossy compression is also referred to as irreversible compression and it can be defined as a type of data encoding (data compression algorithm) in which the data in a file such as an image, is removed by using inexact approximations, in order to reduce the amount of size of a file after decompression.
Since the same algorithm was used to encode and compress these images, the reason why the resulting images have a different length is simply because the amount of size reduction from compression depends on the amount of redundancy in the original image file (data).

Explanation:
Which letter shows the ball when it has the maximum kinetic energy
Answer:
D.
Explanation:
Kinetic energy can be defined as an energy possessed by an object or body due to its motion.
Mathematically, kinetic energy is given by the formula;
[tex] K.E = \frac{1}{2}MV^{2}[/tex]
Where;
K.E represents kinetic energy measured in Joules. M represents mass measured in kilograms. V represents velocity measured in metres per seconds square.Generally, when the final velocity at which a physical object moves is equal to zero (0), then it possess maximum kinetic energy.
Hence, the letter which shows the ball when it has the maximum kinetic energy in the graph attached is D.
What is the result of the following code fragment?
BigInteger a = new BigInteger ("10");
BigInteger b = new BigInteger ("25");
a.multiply(b);
a.add(b);
System.out.println(a);
A. 10
B. 35
C. 250
D. 275
Answer:
D
Explanation:
I don't know the language, but it is clear what is going on.
It looks like you are defining a value for a in both commands.
a.multiply(b); looks like you take the value in a (which is 10) multiply it by 25 and put the result back in a. So so far we have 10 * 25 = 250
Note the next command
a.add(b)
looks like you take the current value in a(which is now 250)
and put the value of b (which has not been changed. It is still 25) and put that in a (which is 250).
The result is 250 + 25 = 275
The answer is D. Since I only understand the logic, if this answer is wrong, I wish you'd leave a note.

1. Light of wavelength 900x10-9 m is emitted by a source. What is its frequency?
therefore the frequency = 6×10^14
The frequency of the light is "[tex]6\times 10^{14}[/tex]".
Given values:
Wavelength,
[tex]\lambda = 900\times 10^{-9} \ m[/tex]
As we know the formula,
→ [tex]Frequency = \frac{C}{\lambda}[/tex]
By substituting the values, we get
→ [tex]= \frac{3\times 10^8}{900\times 10^{-9}}[/tex]
→ [tex]= \frac{10^8}{300\times 10^{-9}}[/tex]
→ [tex]= 6\times 10^{14}[/tex]
Thus the above response is correct.

Answer:
lmasjsjsjssjjssjjssjsjjsksakkalaaooaa
Loan borrowed = $12,000
Percentage of interest on the loan per annum = 14%
We know that :
[tex]\color{hotpink}\tt \: Simple \: interest = \color{plum}\frac{principal \times rate \times time}{100} [/tex]
In this case :
principal = $12000rate = 14%time = 1 yearSimple interest at the end of the first year :
[tex] = \tt \frac{12000 \times 14 \times 1}{100} [/tex]

How do “right to work” states impact workers? (Select all that apply.) They have strengthened unions. They have given unionized workers more protections. They have made it possible to fire workers for any reason or no reason, so long as they are not fired for federally prohibited reasons. They have increased dues-paying union membership by as much as two-thirds. They have banned union-security agreements.
Answer:
"Right-to-work" states impact workers through;
They have banned union-security agreements
Explanation:
"Right-to-work-laws" are state laws that ban union security agreements that allows the trade or labor union to demand employees of an establishment to join the trade or labor union including the obligation of the employer to collect union dues on the union's behalf to reduce the effect of the free-rider problem as the benefit of union negotiation benefits non-union members who are also employees
The "right-to-work laws" prohibits agreements between employers of labor and employees which are members of the unions from stipulating the requirement that the cost of union representation is to be payed for by the workers

Answer:
In a series circuit, the total resistance is equal to the sum of all resistances.
Explanation:
The same current passes through each resistor, so each resistor does its job as you would expect.
