Write a nested loop that prints the following output. 1
1 2 1
1 2 4 2 1
1 2 4 8 4 2 1
1 2 4 8 16 8 4 2 1
1 2 4 8 16 32 16 8 4 2 1
1 2 4 8 16 32 64 32 16 8 4 2 1
1 2 4 8 16 32 64 128 64 32 16 8 4 2 1

Written in Python:

rows = 8

for i in range(1,rows+1):

      for j in range(1,rows):

             print(" ")

      x = 1

      for j in range(1,i):

             print(str(x)+" ",end='')

             x = int(x*2)

      while x >= 1:

             print(str(x)+" ",end='')

             x = int(x/2)

Explanation:

For each row, the print out is divided into two parts.

1. Starts from 1 and ascends to a peak

2. Then descends from the peak to 1

This line initializes the number of rows to 0

rows = 8

This iterates from 1 to the number of rows

for i in range(1,rows+1):

This prints a blank at the end of sequence printed on each line

      for j in range(1,rows):

             print(" ")

This initializes each row element to 1

      x = 1

This iterates the number of item to print on each line depending on the row

      for j in range(1,i):

This prints the row element in ascending order to the peak

             print(str(x)+" ",end='')

This calculates the next element to be printed

             x = int(x*2)

This checks for valid row element to print in descending order to 1

      while x >= 1:

             print(str(x)+" ",end='')

             x = int(x/2)

solution:

this situation is called an ip conflict.

data from a server is sent in small bits called packets. in an ip conflict, some packets will end up in one computer while some other packets will end up in another computer.

so…overall none of the computers get the data as the original message or picture being sent by the server cannot be retrieved with only half the packets. so it will show up as an error.

thus the final answer is d.
