Given an array of integers check if it is possible to partition the array into some number of subsequences of length k each, such that:
Each element in the array occurs in exactly one subsequence
For each subsequence, all numbers are distinct
Elements in the array having the same value must be in different subsequences
If it is possible to partition the array into subsequences while satisfying the above conditions, return "Yes", else return "No". A subsequence is formed by removing 0 or more elements from the array without changing the order of the elements that remain. For example, the subsequences of [1, 2, 3] are D. [1], [2], [3]. [1, 2], [2, 3], [1, 3], [1, 2, 3]
Example
k = 2.
numbers [1, 2, 3, 4]
The array can be partitioned with elements (1, 2) as the first subsequence, and elements [3, 4] as the next subsequence. Therefore return "Yes"
Example 2 k 3
numbers [1, 2, 2, 3]
There is no way to partition the array into subsequences such that all subsequences are of length 3 and each element in the array occurs in exactly one subsequence. Therefore return "No".

Write a CashRegister class that can be used with the RetailItem class that you wrote in Chapter 6's Programming Challenge 4. The CashRegister class should simulate the sale of a retail item. It should have a constructor that accepts a RetailItem object as an argument. The constructor should also accept an integer that represents the quantity of items being purchased. In addition, the class should have the following methods:
• The getSubtotal method should return the subtotal of the sale, which is the quantity multiplied by the price. This method must get the price from the RetailItem object that was passed as an argument to the constructor.
• The getTax method should return the amount of sales tax on the purchase. The sales tax rate is 6 percent of a retail sale.
• The getTotal method should return the total of the sale, which is the subtotal plus the sales tax.
Demonstrate the class in a program that asks the user for the quantity of items being purchased and then displays the sale’s subtotal, amount of sales tax and total.
Answers
Answer:
Following are the code to this question:
import java.util.*; //import package for user input
class RetailItem//defining class RetailItem
{
private String desc;//defining String variable
private int unit;//defining integer variable
private double prices;//defining double variable
RetailItem()//defining default Constructor
{
//Constructor body
}
Output:
The Sub Total value: 199.75
The Sales Tax value: 11.985
The Total value: $211.735
Explanation:
In the above code three class "RetailItem, CashRegister, and Main" is defined, in the class "RetailItem", it defines three variable that is "desc, unit, and prices", inside the class "get and set" method and the constructor is defined, that calculates its value.
In the next step, class "CashRegister" is defined, and inside the class parameterized constructor is defined, which uses the get and set method to return its value.
In the next step, the main class is declared, in the main method two-class object is created and calls its method that are "getSubtotal, getTax, and getTotal".

Explanation:
If the data rate is 10 Mbps and the token is 64 bytes long (the 10-Mbps Ethernet minimum packet size), what is the average wait to receive the token on an idle network with 40 stations? (The average number of stations the token must pass through is 40/2 = 20.) Ignore the propagation delay and the gap Ethernet requires between packets.
Answers
Answer:
1.024x10^-5
Explanation:
To calculate the transmission delay bytes for the token,
we have the token to be = 64bytes and 10mbps rate.
The transmission delay = 64bytes/10mbps
= 51.2 microseconds
A microsecond is a millionth of a second.
= 5.12 x 10^-5
The question says the average number of stations that the token will pass through is 20. Remember this value is gotten from 40/2
20 x 5.12 x 10^-5
= 0.001024
= 1.024x10^-5
Therefore on an idle network with 40 stations, the average wait is
= 1.024x10^-5

Suppose we have 999 records of employees Emp1, Emp2, Emp5, Emp6 and so on up to Emp998 and Emp999 stored in a sequence. Hence, records are nothing but a row in the table. In the employee table, we want to insert new records Emp3 and Emp4 in the sequence, and once we have done insertion we need to update and retrieve the record efficiently to optimize the performance of a database by minimizing the access time when query is being executed.
You are required to solve the problem with the index sequential access method with pros and cons in the given scenario
Answers
The records in the table represents the employee ID of each employee. Assume the table name is EMPLOYEES and the field name of employee IDs is ID, the following SQL query inserts Emp3 and Emp4 into the employees table.
INSERT INTO EMPLOYEES (ID) values (Emp3), (Emp4)
The advantage of using ISAM is that priorities are given to the indices of the records being inserted. So, Emp3 and Emp4 will be inserted immediately after Emp2.
However, a major disadvantage of using ISAM is that it is very expensive to keep the indices in a sequential order;

Although slow start with congestion avoidance is an effective technique for coping with congestion, it can result in long recovery times in high-speed networks, as this problem demonstrates.
A) Assume a round-trip delay of 60 msec (about what might occur across the continent) and a link with an available bandwidth of 1 Gbps and a segment size of 576 octets. Determine the window size needed to keep the pipeline full and the a worst case estimate of the time it will take to reach that window size after a timeout occurs on a new connection using Jacobson’s slow start with congestion avoidance approach.
B) Repeat part (a) for a segment size of 16 kbytes.
Answers
Answer:
The answer to this question can be defined as follows:
In option A: The answer is "13020".
In option B: The answer is "468 Segments".
Explanation:
Given:
The value of round-trip delay= 60 m-second
The value of Bandwidth= 1Gbps
The value of Segment size = 576 octets
window size =?
Formula:
[tex]\text{Window size =} \frac{(\text{Bandwidth} \times \text{round} - \text{trip time})}{(\text{segment size window })}[/tex]
[tex]=\frac{10^9 \times 0.06}{576 \times 8}\\\\=\frac{10^9 \times6}{576 \times 8\times 100}\\\\=\frac{10^7 \times 1}{96 \times 8}\\\\=\frac{10^7 \times 1}{768}\\\\=13020.83[/tex]
So, the value of the segments is =13020.833 or equal to 13020
Calculating segments in the size of 16 k-bytes:
[tex]\text{Window size} = \frac{10^9 \times 0.06}{16,000 \times 8}[/tex]
[tex]= \frac{10^9 \times 0.06}{16,000 \times 8}\\\\ = \frac{10^9 \times 6}{16,000 \times 8 \times 100}\\\\ = \frac{10^4 \times 3}{16 \times 4}\\\\ = \frac{30000}{64 }\\\\=468.75[/tex]
The size of 16 k-bytes segments is 468.75 which is equal to 468.

Implement the generator function scale(s, k), which yields elements of the given iterable s, scaled by k. As an extra challenge, try writing this function using a yield from statement!
def scale(s, k):

>>> s = scale([1, 5, 2], 5)
>>> type(s)
>>> list(s)
[5, 25, 10]
>>> m = scale(naturals(), 2)
>>> [next(m) for _ in range(5)]
[2, 4, 6, 8, 10]
"""
Answers
Answer:
The generator function using yield from:
def scale(s, k):
yield from map(lambda x: x * k, s)
Another way to implement generator function that works same as above using only yield:
def scale(s, k):
for i in s:
yield i * k
Explanation:
The complete program is:
def scale(s, k):
"""Yield elements of the iterable s scaled by a number k.
>>> s = scale([1, 5, 2], 5)
>>> type(s)
<class 'generator'>
>>> list(s)
[5, 25, 10]
>>> m = scale(naturals(), 2)
>>> [next(m) for _ in range(5)]
[2, 4, 6, 8, 10]
"""
yield from map(lambda x: x * k, s)
If you want to see the working of the above generator function scale() as per mentioned in the above comments, use the following statements :
s = scale([1, 5, 2], 5)
print(type(s))
#The above print statement outputs:
#<class 'generator'>
print(list(s))
#The above print statement outputs a list s with following items:
#[5, 25, 10]
The function def scale(s, k): is
def scale(s, k):
yield from map(lambda x: x * k, s)
This function takes two parameters i.e. s and k and this function yields elements of the given iterable s, scaled by k.
In this statement: yield from map(lambda x: x * k, s)
yield from is used which allows to refactor a generator in a simple way by splitting up generator into multiple generators.
The yield from is used inside the body of a generator function.
The lambda function is a function that has any number of arguments but can only have one expression. This expression is evaluated to an iterable from which an iterator will be extracted. This iterator yields and receives values to or from the caller of the generator. Here the expression is x: x * k and iterable is s. This expression multiplies each item to k.
map() method applies the defined function for each time in an iterable.
The generator function can also be defined as:
def scale(s, k):
for i in s:
yield i * k
For the above example
s = scale([1, 5, 2], 5)
def scale(s,k): works as follows:
s = [1, 5, 2]
k = 5
for loop iterates for each item i in iterable s and yields i*k
i*k multiplies each element i.e 1,5 and 2 to k=5 and returns a list
At first iteration, for example, i*k = 1 * 5 = 5, next iteration i*k = 5*5 = 25 and last iteration i*k = 2*5 = 10. So the output. So
s = scale([1, 5, 2], 5) In this statement now s contains 5, 25 and 10
print(list(s)) prints the values of s in a list as: [5, 25, 10] So output is:
[5, 25, 10]
