{
int numOfPebbles = 5;
int[] bucketSizes = {3, 5};
System.out.println(minBuckets(numOfPebbles, bucketSizes));
}
}
Example output:1
The given java code takes in the number of pebbles, numOfPebbles, and an array of bucket sizes, bucketSizes. The output of the function minBuckets will be the minimum number of buckets required to collect exactly the number of pebbles given. The function minBuckets first sorts the bucketSizes array in descending order, so that the largest bucket sizes can be used first.Then, we check for each bucket size, if the current bucket can hold any pebbles, then we decrement the number of pebbles, numOfPebbles, and increase the count of buckets, count. This process is continued until all the pebbles have been collected, or no bucket can be found to collect the remaining pebbles.In the end, if the remaining number of pebbles is not zero, it means that there was no combination of bucket sizes to collect exactly that number of pebbles. In this case, we return -1. Otherwise, we return the count of buckets used to collect all the pebbles.

What is a client-server processing model?A client-server processing model is a distributed application structure that partitions tasks or workload between service providers and service requesters, called clients. Each computer in the client-server model operates as either a client or a server. The server provides services to the clients, such as data sharing, data manipulation, and data storage.
The client requests services from the server, allowing for the distribution of processing responsibilities between the two entities. In this model, the server is responsible for storing data, while the client is responsible for data retrieval. A mainframe configuration is an older computing model that is centralized, where the mainframe performs all computing activities.
All users are linked to the mainframe, which stores all data and applications, as well as handles all processing responsibilities. Mainframes can handle a large amount of data and have a lot of processing power, but they are inflexible and can be difficult to scale.

The integers are entered by the user at the keyboard, one integer at a time
Make a call to a function that checks if the current integer is positive or negative
Make a call to another function that checks if the current integer to see if it's divisible by 2 or not
The above steps are to be repeated, and once an integer equal to 0 is entered, then exit the loop and report each of the counts and sums, one per line, and each along with an appropriate message
NOTE 1: Determining whether the number is positive or negative will be done within a function; and then a call to that function will be made from within the main function. The following is what you are to do within that function: if an integer is positive, add that integer to the Positive_sum increment the Positive_count by one If the integer is negative add that integer to the Negative_sum increment the Negative_count by one
NOTE 2: Determining whether the number is divisible by 2 or not will be done within a second function; and then a call to that function will be made from within the main function. The following is what you are to do within that function: if the integer is divisible by 2 increment the Divby2_count by one if the integer is not divisible by 2 increment the Not_Divby2_count by on
NOTE 3: It's your responsibility to decide how to set up the bold-faced items under NOTE 1 and NOTE 2. That is, you will decide to set them up as function arguments, or as global variables, etc.
Here's an example Python program that processes a set of integers entered by the user and determines if each integer is positive/negative and divisible by 2 or not, using functions:
The Python Programdef check_positive_negative(number, positive_sum, positive_count, negative_sum, negative_count):
if number > 0:
positive_sum += number
positive_count += 1
elif number < 0:
negative_sum += number
negative_count += 1
return positive_sum, positive_count, negative_sum, negative_count
def check_divisible_by_2(number, divby2_count, not_divby2_count):
if number % 2 == 0:
divby2_count += 1
else:
not_divby2_count += 1
return divby2_count, not_divby2_count
def main():
positive_sum = 0
positive_count = 0
negative_sum = 0
negative_count = 0
divby2_count = 0
not_divby2_count = 0
while True:
number = int(input("Enter an integer: "))
positive_sum, positive_count, negative_sum, negative_count = check_positive_negative(
number, positive_sum, positive_count, negative_sum, negative_count)
divby2_count, not_divby2_count = check_divisible_by_2(number, divby2_count, not_divby2_count)
if number == 0:
break
print("Positive count:", positive_count)
print("Positive sum:", positive_sum)
print("Negative count:", negative_count)
print("Negative sum:", negative_sum)
print("Divisible by 2 count:", divby2_count)
print("Not divisible by 2 count:", not_divby2_count)
if __name__ == "__main__":
main()
The check_positive_negative() function takes the current integer, and the sum and count of positive and negative integers seen so far, and returns updated values of the positive and negative sums and counts based on whether the current integer is positive or negative.
The check_divisible_by_2() function takes the current integer and the count of numbers seen so far that are divisible by 2 or not, and returns updated counts of numbers divisible by 2 and not divisible by 2.
The main() function initializes the counters for positive and negative integers and for numbers divisible by 2 or not, and then loops indefinitely, prompting the user for integers until a 0 is entered. For each integer entered, it calls the check_positive_negative() and check_divisible_by_2() functions to update the counters appropriately. Once a 0 is entered, it prints out the final counts and sums for positive and negative integers, and for numbers divisible by 2 or not.

what immediately follows the start frame delimiter in an ethernet frame?
Answer:
The next field in an Ethernet frame after the Start Frame Delimiter (SFD) is the Destination MAC address. This field is 6 bytes long (48 bits) and tells who the frame is meant for. The Source MAC address field comes after the Destination MAC address field. It is also 6 bytes long and shows who sent the frame. After the Source MAC address field, the frame has the Ethernet Type field. This field shows what kind of protocol is in the Ethernet frame's payload. The Payload field comes after the Ethernet Type field. The Payload can be between 46 and 1500 bytes long. The data that is being sent, like an IP packet or another message from a higher-layer protocol, is in the Payload. The last part of an Ethernet frame is the Frame Check Sequence (FCS), which is a 4-byte (32-bit) field that has a checksum for the whole Ethernet frame to make sure it didn't get messed up while being sent.
