Answer:

Explanation:

The if else state is used for checking the condition and if the condition is TRUE and program can execute the statement within the if else.

Initially input_value is 5

then the if statement check the condition 5>5, condition FALSE because 5==5

it not less than 5.

then program move to else if and check condition 5>2, condition TRUE.

then, input_value = 5 + 10=15 execute and update the value to 15.

After that, program terminate the if else statement.

Therefore, the answer is 15.

In a linked chain implementation of a queue, the performance of the enqueue operation

alexdok [17]

Answer:

A.O(1)

Explanation:

In the implementation of queue by using linked chain the performance of the enqueue operation is O(1).We have to maintain two pointers one head and the other tailand for enqueue operation we have to insert element to the next of the tail and then make that element tail.Which takes O(1) time.

A group of statisticians at a local college has asked you to create a set of functions that compute the median and mode of a set

Vanyuwa [196]

Answer:

from functools import reduce

def mean(mylist):

score = reduce(lambda x,y: x + y, mylist)/ len(mylist)

return score

def median(mylist):

sorted(mylist)

list_len = len(mylist) % 2

i = round(len(mylist)/2)

x = len(mylist)//2

if list_len == 0:

median = (mylist[x] + mylist[x+1]) / 2

else:

median = mylist[i]

return median

def mode(mylist):

unique = set(mylist)

unique = list(unique)

collector = [mylist.count(key) for key in unique]

maxi = max(collector)

loc = collector.index(maxi)

return unique[loc]

def main():

scores = input( 'Enter list of numbers: ').split(",")

scores = [int(score) for score in scores]

operation = input('Enter operation: ')

operator = ['mean', 'median', 'mode']

for x in iter(list, 0):

if operation in operator:

break

print("Invalid operation: ")

operation = input('Enter operation')

index_loc = operator.index(operation)

if index_loc == 0:

return mean(scores)

elif index_loc == 1:

return median(scores)

#return np.median(scores) can be used of the defined function

elif index_loc == 2:

#return stats.mode(scores)[0] can be used of the defined function

return mode(scores)

print( main( ) )

Explanation:

The main python function calls conditionally three statistical functions namely mean, median and mode. It prompts for user input for a list of integer numbers and a function name name to return the corresponding result.

Draw a timeline for each of the following scheduling algorithms. (It may be helpful to first compute a start and finish time for

12345 [234]

Answer:

See explanation below

Explanation:

Previos concepts

First Come First Serve (FCFS) "is an operating system scheduling algorithm that automatically executes queued requests and processes in order of their arrival".

Shortest job next (SJN), or the shortest job first (SJF) or shortest "is a scheduling policy that selects for execution the waiting process with the smallest execution time".

Shortest remaining time (SRF) "is a scheduling method that is a preemptive version of shortest job next scheduling'".

Round robin (RR) is an algorithm where the time parts "are assigned to each process in equal portions and in circular order, handling all processes without priority"

Solution for the problem

Assuming the dataset given on the plot attached.

Part a

For this algorithm the result would be:

Job A 0-6

Job B 6-(6+3) = 6-9

Job C 9-(9+1) = 9-10

Job D 10-(10+4) = 10-14

Part b

For this algorithm the result would be:

Job A 0-6

Job C 6-(6+1) = 6-7

Job B 7-(7+3) = 7-10

Job D 10-(10+4) = 10-14

Part c

For this algorithm the result would be:

Job A 0-1 until 14

Job B 2-(2+3) = 2-5

Job C 3-(3+2) = 3-5

Job D 9-(9+5) = 9-14

Part d

For this algorithm the result would be:

Job A 0-2 , 7-9, 12-14

Job B 2-4, 9-10

Job C 4-(4+1) = 4-5

Job D 5-7, 10-12
