Answer:

The answer is (C)

Let’s run the algorithm on a small input to see the working process.

Let say we have an array {3, 4, 1, 5, 2, 7, 6}. MAX = 7

Now for i=0, i < 7/2, here we exchange the value at ith index with value at (MAX-i-1)th index.

So the array becomes {6, 4, 1, 5, 2, 7, 3}. //value at 0th index =3 and value at (7-0-1)th index is 6.

Then for i=1, i < 7/2, the value at index 1 and (7-1-1)=5 are swapped.

So the array becomes {6, 7, 1, 5, 2, 4, 3}.

Then for i=2, i < 7/2, the value at index 2 and (7-2-1)=4 are swapped.

So the array becomes {6, 7, 2, 5, 1, 4, 3}.

Then for i=3, i not < 7/2, so stop here.

Now the current array is {6, 7, 2, 5, 1, 4, 3} and the previous array was{3, 4, 1, 5, 2, 7, 6}.

Explanation:

So from the above execution, we got that the program reverses the numbers stored in the array.

Suppose you are given a sequence that is described by a formula, starting at index n=0. If you need to change the starting index

Arisa [49]

Answer:

$n+1$

Explanation:

Given

$n = 0$ --- starting index

Required

Change the starting index to $n = 1$

We have:

$n = 0$

To change the starting index to k, we simply rewrite as:

$n+k$

<em>In this case; k=1; so, the starting index will be: </em> $n+1$ <em />

A loop that will output every other name in the names list.

Nuetrik [128]

Answer:

names = ['Peter', 'Bruce', 'Steve', 'Tony', 'Natasha', 'Clint', 'Wanda', 'Hope', 'Danny', 'Carol']

numbers = [100, 50, 10, 1, 2, 7, 11, 17, 53, -8, -4, -9, -72, -64, -80]

for index, element in enumerate(names):

if index % 2 == 0:

print(element)

for num in numbers:

if num >= 0:

print(num, end = " ")

count = 0

for i in numbers:

count += i

avg = count/len(numbers)

print("sum = ", count)

print("average = ", avg)

for num in numbers:

if num % 2 != 0:

print(num, end = " ")

Date Time Manipulation Exploration If you start from Jan 1st, 1757, and repeatedly add 8 days, until you hit 1800, how many time

zimovet [89]

Answer:

from datetime import datetime, date, timedelta

def count_weekdays(start_date, add_days, stop_year, weekday):

my_date = start_date

m = 0

while my_date.year != stop_year:

my_date = my_date + timedelta(days = add_days)

if my_date.isoweekday() == weekday:

m += 1

return m

date_val = date(1757,1,1)

try:

date_val = datetime.fromisoformat(input("Enter date in the format yyyy-mm-dd: "))

except ValueError:

print("Wrong isoformat string")

print(count_weekdays(date_val, 8, 1800, 1))

Explanation:

The datetime package of the python programming language has several time modules like the date, datetime, pytz, timedelta, etc, used to manipulate date and time in documents. The function count_weekdays has four parameters and returns the number of a specified weekday in a period of time.
