Write a Python function that will accept as input three string values from a user. The method will return to the user a concaten
Aleks04 [339]

Answer:

Following are the program in python language

def cat_rev(x,y,z): # function definition  

   x=x[::-1]# reverse the first string  

   y=y[::-1]# reverse the second string  

   z=z[::-1]# reverse the third string  

   z=x+y+z;  #concat the string

   return(z)#return the string

   #main method

s=input("Enter the first string:") #read the first string

r=input("Enter the second string:")#Read the second string  

t=input("Enter the third string:")#Read the third string by user

rev1= cat_rev(s,r ,t ) #function calling

print(rev1)# display reverse string

Output:

Enter the first string:san

Enter the second string:ran

Enter the third string:tan

nasnarnat

Explanation:

Following are the description of program

  • In the main function we read the three value by the user in the "s", "r" and "t" variable respectively.
  • After that call the function cat_rev() by pass the variable s,r and t variable in that function .
  • Control moves to the function definition of the cat_rev() function .In this function we reverse the string one by one and concat the string by using + operator .
  • Finally in the main function we print the reverse of the concat string   .

2. Consider a 2 GHz processor where two important programs, A and B, take one second each to execute. Each program has a CPI of
allsm [11]

Answer:

program A runs in 1 sec in the original processor and 0.88 sec in the new processor.

So, the new processor out-perform the original processor on program A.

Program B runs in 1 sec in the original processor and 1.12 sec in the new processor.

So, the original processor is better then the new processor for program B.

Explanation:

Finding number of instructions in A and B using time taken by the original processor :

The clock speed of the original processor is 2 GHz.

which means each clock takes, 1/clockspeed

= 1 / 2GH = 0.5ns

Now, the CPI for this processor is 1.5 for both programs A and B. therefore each instruction takes 1.5 clock cycles.

Let's say there are n instructions in each program.

therefore time taken to execute n instructions

= n * CPI * cycletime = n * 1.5 * 0.5ns

from the question, each program takes 1 sec to execute in the original processor.

therefore

n * 1.5 * 0.5ns = 1sec

n = 1.3333 * 10^9

So, number of instructions in each program is 1.3333 * 10^9

the new processor :

The cycle time for the new processor is 0.6 ns.

Time taken by program A = time taken to execute n instructions

=  n * CPI * cycletime

= 1.3333 * 10^9 * 1.1 * 0.6ns

= 0.88 sec

Time taken by program B = time taken to execute n instructions

= n * CPI * cycletime

= 1.3333 * 10^9 * 1.4 * 0.6

= 1.12 sec

Now, program A runs in 1 sec in the original processor and 0.88 sec in the new processor.

So, the new processor out-perform the original processor on program A.

Program B runs in 1 sec in the original processor and 1.12 sec in the new processor.

So, the original processor is better then the new processor for program B.

A(n) ______ network is a system that attempts to imitate the behavior of the human brain. Group of answer choices advanced neura
larisa [96]

Answer:

Neural Networks

Explanation:

Neural networks are networks that mimic the behaviour of the human brain in which they tend to perform a task without been programmed with the task rule, although the neural network are artificial in nature and they often recognize patterns.

Neutral network have cell that enable them to carry out task together in order to produce a desired result and the cell can only solve a little part of tasks.

The process of ensuring that web pages coded with new or advanced techniques still are usable in browsers that do not offer supp
Leya [2.2K]

Answer:

(C) progressive enhancement

Explanation:

Progressive enhancement is a web design technique that first underlines the main functionality web page and then incorporates increasingly enhanced and advanced features and design levels.

This process enables the users to use and access the basic features of the web pages. These users can use any browser to access the main contents of the web page. Progressive Enhancement also offers an advanced version of the website for those with more advanced and sophisticated computer browsers or faster internet connection.

So the user can access basic features of a web sites as well as the complex features. This process first makes sure the basic intended purpose and main contents of the web site is accessible to all users before adding complex features which are supported by different browsers and devices.

Validation is a process which checks that code of the website is as per the world wide web standards and also checks that content of web pages and design of websites is being properly displayed and the site is accessible. So this is not the correct option.

Technique of altering a web site in a way that it can appear higher in the search engine results is called optimization so this is not a correct option.
