write the definition of the function delete vector duplicates() that passes an stl vector of type int. the function deletes all duplicates. assumption: the vector has at least two elements.
Answers
The function delete_vector_duplicates() that passes an STL vector of type int is,the function uses the sort() function to sort the vector in ascending order, the unique() function to remove consecutive duplicates, and the erase() function to remove the remaining elements from the unique iterator to the end of the vector.
What is the implementation of the function delete_vector_duplicates() for an STL vector of type int in C++?
The definition of the function delete_vector_duplicates() that passes an STL vector of type int is as follows:
`void delete_vector_duplicates(std::vector& vec)`
This function takes a reference to an STL vector of integers (vec) and deletes all duplicate elements. The steps to implement this function are:
Use the unique() function to remove consecutive duplicate elements.
Use the erase() function to remove the unique iterator's return value to the end of the vector.
Here's a sample implementation of the function:
```cpp
#include
#include
void delete_vector_duplicates(std::vector& vec) {
std::sort(vec.begin(), vec.end());
auto unique_end = std::unique(vec.begin(), vec.end());
vec.erase(unique_end, vec.end());
}
```
This implementation first sorts the vector, then uses the unique() function to remove consecutive duplicates, and finally erases the remaining elements from the unique_end iterator to the end of the vector.

hw15-2 determine the force in member dg of the truss in terms of the load l. all internal angles are 60.
Answers
The force in member DG of the truss in terms of the load L is (sqrt(3)/2)*L.
The truss is in static equilibrium, which means that the forces acting on it must balance out. By applying the method of joints, we can solve for the forces in each member. Since all internal angles of the truss are 60 degrees, we can use trigonometry to solve for the forces in each member.
To solve for the force in member DG, we can consider the joint where members DG, EG, and EF meet. We know that the force in member EF is equal to the load L, and we can use trigonometry to find the forces in members DG and EG. Once we have these forces, we can use the method of joints again to find the force in member DG in terms of the load L. The final expression for the force in member DG is (sqrt(3)/2)*L.

Consider two real-time processes with the following parameters:
Process P1 has the period p1 = 100 ms and execution time t1 = 15 ms.
Process P2 has the period p2 = 30 ms and execution time t2 = 20 ms
Both processes are ready to execute at time = 0, and the relative deadlines are equal to periods. The system has only one processor. Answer the following subquestions i.), ii.), iii.): and iv.)
iii.) Now assume we are using RMS and both processes are ready to execute at time = 0. Produce the Gantt chart on a separate piece of paper; and answer the following:
What processes are executed by the CPU from time 0 to 150? Give the exact time intervals. For example, if P1 executes from time = 0 to 10, P2 executes from time = 10 to 15, and the CPU is idle from 15 to 20, you can enter:
P1: 0 – 10: P2 10 – 15: idle: 15 – 20
iv.) Did all the process instances meet their deadlines during the time interval [0 - 150], when we use RMS? If not, what is the first process instance that missed its deadline, and what deadline has been missed?
Answers
iii.) The Gantt chart for RMS scheduling is as follows:
The ProgramTime 0 - 30: P1
Time 30 - 50: P2
Time 50 - 60: P1
Time 60 - 90: P1
Time 90 - 100: P2
Time 100 - 120: P1
Time 120 - 150: P1
The CPU executes process P1 for the first time interval from time 0 to 30. Then, it executes process P2 for the next time interval from time 30 to 50. After that, the CPU goes back to process P1 and executes it from time 50 to 60. Next, the CPU executes process P1 again from time 60 to 90. Then, the CPU executes process P2 from time 90 to 100.
Finally, the CPU executes process P1 for the remaining time intervals from time 100 to 150.
iv.) All the process instances meet their deadlines during the time interval [0-150] when we use RMS. The deadlines for both processes are equal to their respective periods. In this case, P1 has a period of 100 ms and executes for 15 ms, so it has a slack time of 85 ms before its next deadline.
Similarly, P2 has a period of 30 ms and executes for 20 ms, so it has a slack time of 10 ms before its next deadline. Therefore, both processes complete their execution within their respective deadlines.

O(N) is the order of growth execution time of the isFull operation when using the ArrayBoundedQueue class, assuming a queue size of N.TrueFalse
Answers
The given statement "O(N) is the order of growth execution time of the isFull operation when using the ArrayBoundedQueue class, assuming a queue size of N" is false becasue the isFull operation of the ArrayBoundedQueue class has a constant time complexity of O(1), which means its execution time does not depend on the size of the queue. Therefore, its order of growth execution time is O(1), not O(N).
The order of growth execution time of the isFull operation when using the ArrayBoundedQueue class, assuming a queue size of N, is O(1), not O(N). This is because the isFull operation only needs to compare the number of elements in the queue to the maximum capacity of the queue, which can be done in constant time.
Therefore, regardless of the size of the queue, the isFull operation will have the same execution time. The ArrayBoundedQueue class uses an array to store the elements in the queue, and the size of the array is fixed at the time of initialization. Therefore, the isFull operation is simply checking if the number of elements in the queue equals the size of the array.

Split CashRegister class into two classes - Payment and Coin. Payment class will contain enterPayment method, member variables for payment amount and constructors. Coin class will contain member variables for coin values and methods to get coin values.
The CashRegister class has multiple responsibilities - it is responsible for both payment entry and coin values. This violates the Single Responsibility Principle (SRP) and decreases cohesion. To increase cohesion, split CashRegister class into two classes - Payment and Coin. Payment class will contain enterPayment method, member variables for payment amount and constructors.
Coin class will contain member variables for coin values and methods to get coin values. In this way, each class will have a single responsibility and will be more cohesive.

Consider a 4-drive, 200 GB-per-drive RAID array. What is the available data storage capacity for each of the RAID levels, 0, 1, 3, 4, 5, and 6? (Note: when talking about the disk storage capacity, the same data replicated physically to two or more disks counts once, not twice or multiple times).
Answers
The available data storage capacity for each RAID level can be calculated using the following formulas given below.
What is the RAID array?RAID 0:
Available Capacity = Total Capacity of all drives in the array
RAID 1:
Available Capacity = Total Capacity of a single drive (since data is mirrored across all drives, only one drive's capacity is usable)
RAID 3:
Available Capacity = (Number of Drives - 1) * Capacity of Smallest Drive in the array
RAID 4:
Available Capacity = (Number of Drives - 1) * Capacity of Smallest Drive in the array
RAID 5:
Available Capacity = (Number of Drives - 1) * Capacity of Smallest Drive in the array
RAID 6:
Available Capacity = (Number of Drives - 2) * Capacity of Smallest Drive in the array
Given that you have a 4-drive RAID array with 200 GB-per-drive capacity, the available data storage capacity for each RAID level would be:
RAID 0: 4 * 200 GB = 800 GB
RAID 1: 1 * 200 GB = 200 GB
RAID 3: (4 - 1) * 200 GB = 600 GB
RAID 4: (4 - 1) * 200 GB = 600 GB
RAID 5: (4 - 1) * 200 GB = 600 GB
RAID 6: (4 - 2) * 200 GB = 400 GB
Please note that these calculations are approximate and do not take into account other factors such as overhead, parity, or formatting that may affect the actual usable capacity in a RAID array. It is always recommended to consult the documentation or specifications of your specific RAID controller or system for accurate information on available data storage capacity.

why is a stack not good for round robin schedulers ? but a queue is. explain reasons for both.
Answers
A stack is not good for round robin schedulers because it follows the last-in, first-out (LIFO) principle. This means that the most recent process added to the stack will be executed first, which contradicts the round robin principle of giving equal time slices to each process.
On the other hand, a queue is good for round robin schedulers because it follows the first-in, first-out (FIFO) principle. This means that the first process added to the queue will be executed first, and each process will get an equal time slice before moving on to the next process. This aligns with the round robin principle and ensures fair scheduling for all processes.
In summary, a stack is not suitable for round robin schedulers because it doesn't prioritize equal time slices for each process, while a queue is a better choice because it follows the FIFO principle, which aligns with the round robin principle.
