This question concerns the use of a book cypher to encode a message.Write a program called ‘bookcypher.py’ that accepts:1. The file name for a Project Gutenberg book text.2. A message that is to be encoded.3. A file name for output of the encoded version of the message.The program will create an encoded version of the message by replacing its words with the locationsof words in the book.Say, for example, the message is ‘meet me at the usual time and place’, and the Gutenberg text is‘The Importance of Being Earnest’ by Oscar Wilde.• There is an occurrence of ‘meet’ as the 5th word on the 493rd line of the book text.• There is an occurrence of ‘me’ as the 9th word on the 190th line of the text.• There is an occurrence of ‘at’ as the 6th word on the 8th line of the text.• And so on.Representing a word position as a conjunction of the line number and the index of the word withinthe line, we can encode the message as 493-5, 190-9, 8-6, etc.Sample I/O (user input in bold):Enter the book…

please use python language instruction- 1. Read the code from line 123 to line 137. This is the basically the selection.
Remember how we talk about there are certain things about controlling population?
Please explain how we make sure that the population, when going through a selection, does not shrink over generation. You may simply explain this as comments in a Python file as opposed to in a Word file:.
Note that the code from line 123 to line 137 is divided into two small blocks. Use that as 2. The code we've just examined has one functionality of selection. So, we really should wrap that into one function nanied 'select'. Note that in this file there is no class named
'Population'. So, you should make this function a static method that belongs to the class named 'Individual', or a simple function that resides outside the class named
'Individual'. Please think about what the inputs and output of this function are before you start coding. Once you have created the…

Q1.  What is the difference between static and extern storage class? Give suitable examples in support of your answer. Q2.  Write a program to take input for a number, if the number is palindrome, then display its half on the screen, otherwise take input for 2 more numbers, and display their product on the screen. Use minimum two functions including main function

4.27 LAB: Palindrome (JAVA)   A palindrome is a word or a phrase that is the same when read both forward and backward. Examples are: "bob," "sees," or "never odd or even" (ignoring spaces). Write a program in java whose input is a word or phrase, and that outputs whether the input is a palindrome. Ex: If the input is: bob the output is: palindrome: bob Ex: If the input is: bobby the output is: not a palindrome: bobby Hint: Start by just handling single-word input, and submit for grading. Once passing single-word test cases, extend the program to handle phrases. If the input is a phrase, remove or ignore spaces. Code starts here: import java.util.Scanner; public class LabProgram {   public static void main(String[] args) {      /* Type your code here. */   }}

Instruction: Answer question 4 (a,b & c) only (1) Create a C++ project for your assignment 3, with the name format prescribed in the Information section. Add a source file and name it SwapCount. In this file, write the C++ program that will perform the tasks specified in question 2.(2) Declare and implement a function called sortSwapCount that passes three parameters, the array, the size and the reference of proportion, and returns the count. The functiondeclaration is int sortSwapCount(int data[], int size, double& proportion) (i) The function sorts the integers in data[] in ascending order using the bubble sort method. The purpose is to count or determine the number of exchanges (swaps) made by the bubble sort algorithm.  (ii) The expected number of sorting swaps (expectedSwapCount) is size * (size - 1) if the array was unsorted. Calculate the proportion of the array status by first converting (or casting) the integers, swapCount and expectedSwapCount into floating-point,…

6.7 In Python, A palindrome is a word or a phrase that is the same when read both forward and backward. Examples are: "bob," "sees," or "never odd or even" (ignoring spaces). Write a program whose input is a word or phrase, and that outputs whether the input is a palindrome. Ex: If the input is: bob the output is: bob is a palindrome Ex: If the input is: bobby the output is: bobby is not a palindrome Hint: Start by removing spaces. Then check if a string is equivalent to it's reverse.

Handwritten please.   Create Turing machines based on the following specifications. The Turing machine must be expressed as files that can be used as inputs for the Turing machine simulator described below.  Design a Turing machine on the input alphabet {d,e,f}{d,e,f} that accepts strings represented using this Python regular expression that uses back references: r'^([de]*)f\1$' For this machine, the final tape output does not matter. You will need to modify the tape in order to complete this exercise.

Interestingly some numbers can be perfectly represented in Base 10, but not in Base 2. An example is one-tenth (in Base 10, this is 0.1; in Base 2 this is a repeating decimal. Suppose we set both f and g to one-tenth using the statements below. f = 0.1; g = 0.1; Answer the following questions. For each, mark the best answer. Which will be closer to the actual value of one-tenth? f g Which can hold higher values? f g Which takes more memory? f g When using real values I should always use type double, to be safe. True False

Instruction: Read, understand, and answer the problems stated below. Consider and understand the scenario that follows. Debug the program in order for it to run as stated in its specification. The program below, when ran, will let the user roll a pair of dice n-times (i.e. generate a number between I and 6), where n is a positive integer entered by a user. The program then outputs the pair of numbers rolled by the dice, as well as the sum of the numbers rolled by each pair of dice. The pairs of numbers are stored in a 2-dimensional array, and the sum of each pair are stored in a single-dimensional array. Underline the changes you have made.

Please solve the following in Java Sean can't remember where he put an important file on his computer. He desperately needs the file tonight to finish his homework, since he procrastinated all day by playing computer games. Unfortunately, his computer has gotten fried from all the gaming, and can no longer perform automatic searches for files. He therefore has to look for the file manually.Since he tends not to use subdirectories too much,he knows his best bet is to look for the file first in the root directory ("/"), and next in directories only one level deep (for example, "/Games/"), and so forth, checking the "deepest" directories last. His computer still has enough fire power to run some simple programs, so he has asked you to code for him a simple algorithm to sort all of the directories on his computer. ThealgorithmshouldtakeaString[]dirsasaninputand should sort dirs first by directory depth, and then lexicographically for each depth. So "/d/e/" comes before "/a/b/c/", but not…
