explain the benefits of object oriented design

Answers

Answer:

Maintainability, Reusability , Encapsulation , Scalability

Explanation:

Maintainability --> Breaks down large and complex systems into smaller parts which are easier to manage. With each object having clear purpose.

Reusability --> Once a object is tested it can be reused in different aspect of systems allowing code duplication to decrease.

Encapsulation --> Reduces the risk of unintended interference since internal workings of an objects are hidden from other objects.

Scalability --> New objects can be added to the system without having to change the existing code. (using objects allows code to be in a generic format thus easier code addition in the form of objects)

write a program using one-dimensional array that get the smallest input value from the given array. Array size is 10.

Answers

Here is an example of a program that uses a one-dimensional array to find the smallest input value from an array of size 10 in Python:

def find_smallest_value(arr):

smallest = arr[0] #initialize the first element of array as the smallest

for i in range(1, len(arr)): # start the loop from 1 as we already have the first element as the smallest

if arr[i] < smallest:

smallest = arr[i]

return smallest

arr = [5, 2, 8, 9, 1, 3, 4, 6, 7, 10]

print("The smallest value in the array is:", find_smallest_value(arr))

This program defines a function find_smallest_value() that takes an array as an input. Inside the function, it initializes the first element of the array as the smallest. Then it uses a for loop to iterate through the array, starting from the second element. For each element, it checks if the current element is smaller than the current smallest value. If it is, it updates the smallest value. After the loop is finished, it returns the smallest value. In the last line, we call the function and pass the array and print the result.

You can change the elements of the array and test it again to see the result.

a) Main memory is byte addressable?
b) Main memory is word addressable?
3. How many bits are required to address a 1M × 8 main memory if:
a) Main memory is byte addressable?
b) Main memory is word addreeable?

Answers

Answer:

a) 23 b) 21a) 43 b) 42a) 0 b) 0

Explanation:

1) How many bits is needed to address a 2M * 32 memory

2M = 2^1*2^20, while item =32 bit long word

hence ; L = 2^21 ; w = 32

a) when the memory is byte addressable

w = 8; L = ( 2M * 32 ) / 8 = 2M * 4

hence number of bits = log2(2M * 4)= log2 ( 2 * 2^20 * 2^2 ) = 23 bits

b) when the memory is word addressable

W = 32 ; L = ( 2M * 32 )/ 32 = 2M

hence the number of bits = log2 ( 2M ) = Log2 (2 * 2^20 ) = 21 bits

2) How many bits are required to address a 4M × 16 main memory

4M = 4^1*4^20 while item = 16 bit long word

hence L ( length ) = 4^21 ; w = 16

a) when the memory is byte addressable

w = 8 ; L = ( 4M * 16 ) / 8 = 4M * 2

hence number of bits = log 2 ( 4M * 2 ) = log 2 ( 4^1*4^20*2^1 ) ≈ 43 bits

b) when the memory is word addressable

w = 16 ; L = ( 4M * 16 ) / 16 = 4M

hence number of bits = log 2 ( 4M ) = log2 ( 4^1*4^20 ) ≈ 42 bits

3) How many bits are required to address a 1M * 8 main memory

1M = 1^1 * 1^20 , item = 8

L = 1^21 ; w = 8

a) when the memory is byte addressable

w = 8 ; L = ( 1 M * 8 ) / 8 = 1M

hence number of bits = log 2 ( 1M ) = log2 ( 1^1 * 1^20 ) = 0 bit

b) when memory is word addressable

w = 8 ; L = ( 1 M * 8 ) / 8 = 1M

number of bits = 0

Tony Stark wants to build a 1000 meter high tower as quickly as possible. He has unlimited resources and an unlimited budget and is willing to spend any amount to get the job done.

He has chosen to build the tower with blocks that are 100 meters long and 100 meters wide, but only 1 meter tall. The blocks interlock on top and bottom (like legos). They cannot be stacked sideways.

Using special lifters, putting one block on top of another block takes one week. Putting a stack of up to 100 blocks on top of another stack of 100 or less also takes a week. If either stack is more than 100, it takes two weeks.

What is the shortest amount of time that it will take to build the tower?
Why is your answer the shortest amount of time?
How did you solve the problem? What is your algorithm?

Answers

Answer:

10 weeks

Explanation:

100 blocks stacked over 10 weeks will be 1000 meters tall

1000 divided by 100 equals 10

The shortest amount of time it will take to build the tower is 10 weeks.

How can the tower be built in the shortest amount of time?

To minimize the construction time, Tony Stark can follow a strategy where he first builds 10 stacks of 100 blocks each, which will take 10 weeks.

Then, he can stack these 10 stacks on top of each other in a single week since they are all 100 blocks or less. By doing so, he can complete the tower in a total of 10 weeks.

Answer: Three of the professions that use simulation training programs are healthcare, aviation, and military.

Explanation: Simulation training programs are educational interventions that use realistic scenarios and environments to mimic real-world situations and challenges. Simulation training programs aim to enhance the knowledge, skills, and attitudes of learners in a safe and controlled setting, where they can practice, receive feedback, and improve their performance. Simulation training programs can also facilitate teamwork, communication, problem-solving, and decision-making skills among learners.

Simulation training programs are widely used in various professions that require high levels of technical competence, situational awareness, and crisis management. Some examples of these professions are:

Healthcare: Healthcare professionals use simulation training programs to learn and practice clinical skills, procedures, and interventions on mannequins, task trainers, virtual patients, or standardized patients (actors who portray patients). Simulation training programs can also help healthcare professionals develop teamwork and communication skills in interprofessional scenarios, such as cardiac arrest, trauma, or obstetric emergencies. Simulation training programs can improve patient safety and quality of care by reducing medical errors, enhancing clinical competence, and increasing confidence among healthcare professionals.Aviation: Aviation professionals use simulation training programs to learn and practice flight skills, procedures, and maneuvers on flight simulators, which are devices that replicate the cockpit and environment of an aircraft.

Algorithm:

Suppose we have n jobs with priority p1,…,pn and duration d1,…,dn as well as n machines with capacities c1,…,cn.

We want to find a bijection between jobs and machines. Now, we consider a job inefficiently paired, if the capacity of the machine its paired with is lower than the duration of the job itself.

We want to build an algorithm that finds such a bijection such that the sum of the priorities of jobs that are inefficiently paired is minimized.

The algorithm should be O(nlogn)

My ideas so far:

1. Sort machines by capacity O(nlogn)
2. Sort jobs by priority O(nlogn)
3. Going through the stack of jobs one by one (highest priority first): Use binary search (O(logn)) to find the machine with smallest capacity bigger than the jobs duration (if there is one). If there is none, assign the lowest capacity machine, therefore pairing the job inefficiently.

Now my problem is what data structure I can use to delete the machine capacity from the ordered list of capacities in O(logn) while preserving the order of capacities.

Your help would be much appreciated!

Answers

To solve the problem efficiently, you can use a min-heap data structure to store the machine capacities.

Here's the algorithm:

Sort the jobs by priority in descending order using a comparison-based sorting algorithm, which takes O(nlogn) time.

Sort the machines by capacity in ascending order using a comparison-based sorting algorithm, which also takes O(nlogn) time.

Initialize an empty min-heap to store the machine capacities.

Iterate through the sorted jobs in descending order of priority:

Pop the smallest capacity machine from the min-heap.

If the machine's capacity is greater than or equal to the duration of the current job, pair the job with the machine.

Otherwise, pair the job with the machine having the lowest capacity, which results in an inefficient pairing.

Add the capacity of the inefficiently paired machine back to the min-heap.

Return the total sum of priorities for inefficiently paired jobs.

This algorithm has a time complexity of O(nlogn) since the sorting steps dominate the overall time complexity. The min-heap operations take O(logn) time, resulting in a concise and efficient solution.
