Two files named numbers1.txt and numbers2.txt both have an unknown number of lines, each line consisting of a single positive in

teger. Write some code that reads a line from one file and then a line from the other file. The two integers are multiplied together and their product is added to a variable called scalar_product which should be initialized to zero. Your code should stop when it detects end of file in either file that it is reading. For example, if the sequence of integers in one file was "9 7 5 18 13 2 22 16" and "4 7 8 2" in the other file, your code would compute: 4*9 + 7*7 + 8*5 + 2*18 and thus store 161 into scalar_product.

Answer:

see explaination for program code

Explanation:

scalar_product = 0

li=[]

li2=[]

#reading numbers1.txt and numbers2.txt intoli and li2 respectively

with open('numbers1.txt') as n1, open('numbers2.txt') as n2:

for line1 in n1:

li.append(int(line1))

for line2 in n2:

li2.append(int(line2))

#storing min list size into variable l

a=len(li)

b=len(li2)

if a<b:

l=a

else:

l=b

#calculating scalar product

for i in range(l):

scalar_product=scalar_product+li[i]*li2[i]

print("scalar product is",scalar_product)

vovikov84 [41]

Answer:

D. System/Application Domain

Explanation:

A system or application domain is used by an organization to supports its IT infrastructure, holding all the business critical mission system, applications and data. All the resources of the company are contained in this domain, and is accessible by a member.

LAN to WAN domain links the company's infrastructure or local area network to a wide area network or the internet. The WAN domain simply holds publicly the data of an organisation, while remote access domain is meant for a small group of workers in the office or working from home.

In your own words, describe the structure and function of both the stack and queue data structure and discuss how they are diffe
Kobotan [32]

Answer:

Following are the answer to this question:

Explanation:

Stack:

The stack data structure is used to create method, parsing, analysis of expression, and tracking. This data type uses the LIFO system, which stands from the Last In First Out. This data structure operates on the top side. In this data structure, it performs two methods, that are "push() and pop()" method and the time complexity of the stack data structure O(1).

Example of Stack:

import java.util.*;//import package

 public class Main //defining class Main

{      

public static void main (String[] ag)//defining main method  

  {

     ArrayDeque<Character> stack = new ArrayDeque<Character>();//creating Character array ArrayDeque  

       stack.push('A'); //add value in stack  

      stack.push('B');//add value in stack  

      stack.push('B'); //add value in stack  

      System.out.println("First Insert:"+stack); //print value         stack.pop();//remove value from stack    

    System.out.println("After removing element: "+stack); //print value         stack.push('B'); //add value in stack    

    stack.pop();//remove value from stack      

 System.out.println("final value: "+stack); //print value    

}

}

Output:

First Insert:[B, B, A]

After removing element: [B, A]

final value: [B, A]

Queue:

The queue data structure is an abstract type, it is similar to the stacks data structure. It is open at both ends when opposed to lines. It follows the FIFO method, which stands for the First-In-First-Out method, At one end data is inserted and at the other end, it deletes the data and the time complexity of the queue data structure O(1).

Example of Queue:

import java.util.*;//import package  

public class Main//defining a class queue

{  

    public static void main(String[] ars)//defining main method

    {  

      LinkedList<Integer> que= new LinkedList<Integer>();//defining integer array LinkedList    

      for (int i = 0; i < 5; i++)//defining fo loop to add value in queue  

     {    

        que.add(i); //use add method to insert value        

}        

System.out.println("Queue value: "+ que); //print queue value      

  int remove= que.remove(); //remove value from the queue          System.out.println("after removing value from queue: "+ remove);//removing element from queue  

      System.out.println(que);  //after removing the element print value  

  }

}  

Output:

Queue value: [0, 1, 2, 3, 4]

after removing value from queue: 0

[1, 2, 3, 4]

¿por que la toria de lamarck sobre el alargamiento del cuello de las jirafas por el esfuerzo continuado no pasara a sus descendi
Paha777 [63]

Respuesta: Los caracteres adquiridos no se transmiten genéticamente porque no modifican el ADN de los organismos

Explicación:

Jean-Baptiste Lamarck al igual que Charles Darwin, propuso una teoría sobre la evolución que explicaba cambios en los organismos a través del tiempo. La teoría de Lamarck se enfocaba en condiciones en el ambiente que propiciaban cambios en los organismos. Un ejemplo de esto son las jirafas, que de acurdo a Lamarck tenían cuellos largos debido al esfuerzo continuado para comer hojas de árboles altos. Esto significa que la característica de cuello largo era adquirido por las jirafas durante su vida y según Lamarck se transmitiría a sus descendientes.

Sin embargo, se ha comprobado que los caracteres adquiridos no modifican el ADN de los organismos, por ejemplo las cirugías estéticas no cambian el ADN de una persona y por esta razón no son transmitidos a sus descendientes. Por el contrario, en las poblaciones de organismos ciertas características prevalencen en el tiempo debido a la selección natural. Esto significa que el cuello de las jirafas es el resultado que el cuello largo sea una característica beneficiosa que ha prevalecido debido a la selección natural y no de características adquiridas que son transmitidas a descendientes.
