In Python please help with the following: a) Write a class in Python called Vector2d whose initializer receives two numbers: x,y. Define an instance method called translateby that receives two numbers: dx and dy and translates the vector by dx and dy. Translating vector v by dx and dy makes the vector's x and y incremented by dx and dy, respectively. For example: (1, 2) translated by 3, and 4 results in (4,6). Define a static method called sum that receives two vectors and returns a new vector whose value equals the sum of the two vectors. B) Test your code by implementing the following: • Create a vector v1, instantiate it with (1, 2). • Create a vector v2, instantiate it with (2, 4). • Calculate the sum of the two vectors in v3. • Translate v3 by 1 and 2. • Print v3's coordinates. It prints 4, 8.

1. Copy constructor to create a new bag using a bag passed in. However, please note that the order in which this constructor stores the items is the reverse of the original order (in which the items appear in the passed-in bag). 2. Function addVector, which takes a vector as the only parameter, to add the entries from the vector to the new bag. 3. Function removelastThree, which takes an item as the only parameter, to remove the last three occurrences of the item in the bag. It is OK to make assumptions. Please state our assumptions, if any. Please explain in detail how each step works and what the new bag contains after each of the steps is executed. - Please use linked Nodes diagrams in our answer. - Please use the data below in our explanation. 1. Passed-in bag: 2. Passed-in vector: 'e', 'n', 'g', ",'n', 'e', 'e', 'r 'e', ", 'e', 'c', 't, 'r', 'i, 'c', 'a', 'I' 3. Passed-in item: 'e' Copy constructor (reverse order) function addVector

In c++ iv read from a text file containing integers Example 11,1 22, 3 12, 4 And stored each colum in a vector vectorx and vectory How can i make a class for x integers and class for y integers I will use this classes to compare these x and y integers

There are two tasks to this assignment. Task 1 Currently you are using composition by creating an instance of a vector / ArrayList inside your AddressBook. This works fine but if we really think about it, an AddressBook is a collection like a stack or a queue or a vector for that matter.  Your task is to: C++ derive AddressBook from vector. In other words, use the vector as a base class and derive AddressBook from it.  This means that you will need to remove the Vector from the private section of your class. Java derive AddressBook from ArrayList. In other words, use the ArrayList as a base class and derive AddressBook from it.  This means that you will need to remove the ArrayList from the private section of your class. You are going to have to make some fundamental changes to your AddressBook so that you are using the vector / ArrayList functionality to store and retrieve people. In other words, you should be accessing the ArrayList / vector using this. C++ people, don’t forget you…
