Answer:

3 select inputs are required to select a specific input between 5 inputs.

Explanation:

Multiplexer is used to select the inputs from different inputs to a single output. There are many types of multiplexers for different number of inputs selection. 1. 2x1 is the type of multiplexer where 2 inputs and 1 output. This is used to select between these inputs. There is one more pin to select the input between these two inputs that is called <em>select </em>input.

2. Another type is 4x1 multiplexer. There are 4 inputs and one output. In this type of multiplexer 2 select pins are used for selection of input bits between these 4 inputs.

For more than 4 inputs and less than 8 inputs, 8x1 multiplexer is used. this multiplexer uses three inputs for selection purpose.

Write a program that generates 1,000 random integers between 0 and 9 and displays the count for each number. (Hint: Use a list o

masya89 [10]

Answer:

import random

count0, count1, count2, count3,

count4, count5, count6, count7,

count8, count9, i = [0 for _ in range(11)]

while i < 1000:

number = random.randint(0,9)

if number == 0:

count0 = count0 + 1

if number == 1:

count1 = count1 + 1

if number == 2:

count2 = count2 + 1

if number == 3:

count3 = count3 + 1

if number == 4:

count4 = count4 + 1

if number == 0:

count5 = count5 + 1

if number == 6:

count6 = count6 + 1

if number == 7:

count7 = count7 + 1

if number == 0:

count8 = count8 + 1

if number == 9:

count9 = count9 + 1

i = i+1

print("0's: "+ str(count0) + "\n"+ "1's: "+ str(count1) + "\n"+

"2's: "+ str(count2) + "\n"+ "3's: "+ str(count3) + "\n"+

"4's: "+ str(count4) + "\n"+ "5's: "+ str(count5) + "\n"+

"6's: "+ str(count6) + "\n"+ "7's: "+ str(count7) + "\n"+

"8's: "+ str(count8) + "\n"+ "9's: "+ str(count9) + "\n")

Explanation:

- Initialize variables to hold the count for each number

- Initialize <em>i</em> to control the while loop

- Inside the while loop, check for the numbers and increment the count values when matched.

- Print the result

The following code processes a file containing five positive numbers. What will the variable $result contain after the code is e

Tanzania [10]

Answer:

highest of five numbers in the file

Explanation:

This code reads the file "some-file.txt" and saves the result in variable "somefile"
The runs a for loop for a count of 5.
In each loop it compares the current value of the file with the value of the variable result and if the result is true it updates the value of the variable result.
At the end of this code the variable result will contain the highest value in the file "some-file.txt" and print it.
