IN PYTHON :

Write one program that will compute both the Least Common Multiple, and the Greatest Common Factor of two numbers inputted by a user.

The program will display all factors and multiples of the two numbers.  

When displaying the multiples of the numbers, only display up to the first input times the second input. \

Use functions to computer the answers.  

Loop the program so that the user can enter two new numbers after each try.

Consider the following schema:

product (pname, price, category, manufacturer)

Purchase (buyer, seller, store, product)

class Solution {
public:
vector<int> inorderTraversal(TreeNode* root) {
  
}
};

Given the root of a binary tree, return the inorder traversal of its nodes' values.

Example 1:

Input: root = [1,null,2,3]
Output: [1,3,2]

Example 2:

Input: root = []
Output: []

Example 3:

Input: root = [1]
Output: [1]

Example 4:

Input: root = [1,2]
Output: [2,1]

Example 5:

Input: root = [1,null,2]
Output: [1,2]

Constraints:

• The number of nodes in the tree is in the range [0, 100].
• -100 <= Node.val <= 100

This program is in C++

Please kindly make sure that the output exactly matches the test case so I can vote a thumbs up. If it doesn't the program is wrong.

Test Cases and the given code are given after the prompt

Prompt:

Modify the given code to:

1.. Store the data in Binary file and access it   in Random Access mode.  

2.Replace Class with Structure for Employee and Department.

3. Inside each structure, replace all string variables with array of characters. please read the chapter 12(More about characters and strings). Though we do not have homework on this, the knowledge from this chapter will help you do the final exam project.

4. Make Employee and Department editable. That means, the user should be able to edit a given Employee and Department. Youc an allow the user to edit Employee name, age etc and assign him/her to different department. Similarly department name and department head can be changed. However, do not allow the uesr to Employee ID in Employee file and Department ID in department file.

5. Please note that the data will no longer be stored in the array as it was in the given code. Instead, it should be written to the file as soon as you collect the data from the user. If you are editing a record, read it from the file,collect new data from the user, store the record back to the file in the same place it was found inside the file. That means, the menu will not have options to save data to file or read data from file. Also, this should provide the ability for user to create unlimited number of employees and departments unlike in given code where you allowed only limited number of departments and employees.

The Gettysburg Address

President Abraham Lincoln

November 19, 1863

"Fourscore and seven years ago our fathers brought forth on this continent a new nation, conceived in liberty and dedicated to the proposition that all men are created equal.

Now we are engaged in a great civil war, testing whether that nation, or any nation so conceived and so dedicated, can long endure. We are met on a great battlefield of that war. We have come to dedicate a portion of that field as a final resting-place for those who here gave their lives that that nation might live. It is altogether fitting and proper that we should do this. But, in a larger sense, we cannot dedicate — we cannot consecrate — we cannot hallow — this ground. The brave men, living and dead, who struggled here have consecrated it, far above our poor power to add or detract. The world will little note, nor long remember what we say here, but it can never forget what they did here. It is for us the living, rather, to be dedicated here to the unfinished work which they who fought here have thus far so nobly advanced. It is rather for us to be here dedicated to the great task remaining before us — that from these honored dead we take increased devotion to that cause for which they gave the last full measure of devotion — that we here highly resolve that these dead shall not have died in vain — that this nation shall have a new birth of freedom and that government of the people, by the people, for the people, shall not perish from the earth."

Based on the document Gettysburg Address, what actions did enslaved people take during the Civil War and how were they treated by the Union army? How did the Emancipation Proclamation and the Gettysburg Address, change the purpose of the Civil War?

In your opinion, what are companies that use sales promotion (offline and online) effectively? Based on what we learned in Chapter 13, tell us the name of the company and its sale promotion strategies.

Coloured objects, red ones, blue ones, whatever. For this purpose, one assumes that light is waveforms as opposed to particles of energy. Traditional theories state that a green object appears green because it reflects green light and absorbs other frequencies: red, likewise. What property does the substance have to cause it to reflect certain wavelengths and to absorb others? Is this related to luminescence and fluorescence?
