One disadvantage each for list, array, and queue data structures are:
The list is constrained in that additions can only be made at the end.Because array items are kept in contiguous memory, insertion and deletion operations are expensive.Limited Room.What are the disadvantages of simple queue in data structure?It is difficult to quickly search the queue. You must begin at the very end and might need to keep another queue. Don't even consider utilizing a queue if you have data that you want to make searchable in the future. It is difficult to add or remove items from the queue's middle.

It is to be noted that the essential parts of a mathematical function in spreadsheets are:
input parameters (Option A)variables (Option B)expressions (Option D).What is a mathematical function?A mathematical function is a rule that determines the value of a dependent variable based on the values of one or more relationships between the independent variable. A function can be represented in a variety of ways, including a table, a formula, or a graph.
When it comes to variables and spreadsheets, "it's garbage in garbage out." The computer has no way of knowing which variable is the right one to enter. This remains the solve prerogative of the Spreadsheet user, hence it's importance.

You need to contact a client on the phone. You have estimated that you have a 70% chance of contacting the client on the first call. If you don't, you estimate that you have a 20% chance of contacting the client on a subsequent call in the next hour. Which of the following is true?
a. The probability that you will need at most two calls to contact the client is 0.90.
b. The probability that you will fail on call 1 but will succeed on call 2 is 0.06.
c. The probability that you will fail on call 1 but will succeed on call 2 is 0.50.
d. The probability that you will need at most two calls to contact the client is 0.80.
From the information provided, the correct answer is Option B - " The probability that you will fail on call 1 but will succeed on call 2 is 0.06." See further explanation below.
What is probability?Probability is an area of mathematics that deals with numerical representations of how probable an event is to occur or how likely a statement is to be true. The probability of an occurrence is a number between 0 and 1, where 0 denotes the event's impossibility and 1 represents certainty.
Hence,
P(E) = Number of favorable outcomes/Total Number of outcomes.
Step I
From the information provided, the probability of failing to contact the client on the first call can be computed as:
30% = 0.3
[Rationale is based on estimation. If there is an estimated 70% chance of success, then the chance of failure is 30% which is 0.3]
Step II
The probability of contacting the client on the second call is: 0.2 or 20% [Rationle is as per the given assumption.]
If the two scenarios above hold out because they are mutually exclusive events, the probability, therefore, that you will fial on call 1 and succeed on call two becomes:
0.3 x 0.2
= 0.06
Hence, Option B is the correct answer.

Hello, I desperately need help in python with this question. I have tried everything: This is the question also:
4.24 LAB: Even/odd values in a list
Write a program that reads a list of integers, and outputs whether the list contains all even numbers, odd numbers, or neither. The input begins with an integer indicating the number of integers in the list. The first integer is not in the list.
Ex: If the input is:
5
2
4
6
8
10
the output is:
all even
Ex: If the input is:
5
1
-3
5
-7
9
the output is:
all odd
Ex: If the input is:
5
1
2
3
4
5
the output is:
not even or odd
Your program must define and call the following two functions. is_list_even() returns true if all integers in the list are even and false otherwise. is_list_odd() returns true if all integers in the list are odd and false otherwise.
def is_list_even(my_list)
def is_list_odd(my_list)
This is what I came up with:
def GetUserValues():
n = int(input())
numbers = []
for i in range(n):
numbers.append(int(input()))
return numbers
def IsListEven(myList):
for n in myList:
if n % 2 == 1:
return False
return True
def IsListOdd(myList):
for n in myList:
if n % 2 == 0:

When posting code, it's better to copy the code into a text editor(such as notepad), save it as a text file and upload this through the clip icon on the bottom right of the brainly toolbar (at the bottom)
Anyway, I copied your code and properly formatted it and it works fine
Since I cannot see the formatting, I am assuming that your return True statements are improperly indented. These statements should go with the for loop, not the if statement
Here is the wrong way to define
def IsListEven(myList):
for n in myList:
if n % 2 == 1:
return False
return True #this belongs to the if statement
If you write your code as follows, the return True goes with the if statement. That means it will return from the function as soon as it finds an even number without checking the rest of the list. For example if the list was [2, 4, 6, 8, 1], the function will return True on the first element in the list without going through all the elements
The correct way is:
def IsListEven(myList):
for n in myList:
if n % 2 == 1:
return False
return True # now belongs to the for loop

Parallel Computing and Distributed Computing
Sequential computing has been great, but computer scientists need every speed and storage advantage they can get. Clever computer scientists have found even more efficient ways to use computer hardware for certain types of problems.
parallel Computing
Parallel computing is the use of a computer that performs multiple instructions at the same time. The programs used for parallel computing must be designed so they can be broken down into smaller independent parts that each processor can work on.
Parallel computing uses multiple computing cores. A computing core is one processor in the CPU. Parallel computers will have many different processors in their CPUs instead of just one.
Speedup in Parallel Computing
The advantage of a parallel computing solution over a sequential computing solution can be measured in speedup. Speedup is the amount of time used to perform a task with sequential computation divided by the amount of time used to perform the same task with parallel computation.
For example, imagine that you run a program on a sequential computer and it takes 10 minutes to complete. Next, you run the same program on a parallel computer and it takes 5 minutes to complete. You would divide the 10 by the 5 and come up with a speedup of 2. This means your program is two times faster on a parallel computer.
Distributed Computing
Many computer problems are so complex that they take an extremely long time to run on one computer. Distributed computing is the use of multiple computers to solve a problem. Distributed computing is like parallel computing but with many different computers; parallel computing is the use of one computer with many different processors.
QUESTION:
A program takes 10 minutes to compute sequentially and has a speedup of 2 on a parallel computer, meaning it takes how many minutes. ??
Answer:
5 minutes
Explanation:
It is there in the section on Speedup in Parallel Computing
For example, imagine that you run a program on a sequential computer and it takes 10 minutes to complete. Next, you run the same program on a parallel computer and it takes 5 minutes to complete. You would divide the 10 by the 5 and come up with a speedup of 2
Write a recursive function encode that takes two Strings as an input. The first String is the message
to be encoded and the second String is the key that will be used to encode the message. The function
should check if the key and message are of equal length. If they are not the function must return the
string “Key length mismatch!” Otherwise the function must get the ASCII value of each character in
the key string and check if it is divisible by 2 if it is then the respective character in the message will be
encoded by getting the ASCII value of that character and adding 5. If corresponding key character it is
not divisible by 2 then 3 is added instead.

Parallel computing is to distributed computing as multiple processors are to which of the following?
a - software
b- a tablet computer
c - multiple computers
d - single processor
Parallel computing is to distributed computing as multiple processors are to "single processor" (Option D).
What is the advantage of Parallel computing?
It is to be noted that Parallel computing on a single computer use many processors to execute work in parallel, whereas distributed parallel computing employs numerous computing devices to accomplish such tasks.
Parallel computing refers to the study, design, and execution of algorithms in order to solve a problem using many processors. The basic goal is to solve a problem quicker or larger issue in the same amount of time by sharing the work among many processors.
Parallel computing has the advantage of allowing computers to run code more effectively, saving time and money by sorting through "huge data" faster than ever before. Parallel programming can also handle more difficult issues by pooling resources.
One of the benefits of parallel processing is not autonomy. Parallel processing is a computer strategy in which discrete elements of a bigger difficult operation are divided and processed on many CPUs at the same time, saving processing time.
