python 3, Write a program for displaying information about COVID-10 positive cases around the world. Start by implementing a data structure that stores the following information about the number of COVID-19 cases in countries at three different timestamps: Lebanon had 25 cases at time stamp 1, 1000 cases at time stamp 2 and 2000 cases at time stamp 3. France had 100000 cases at time stamp 1, 123000 cases at time stamp 2 and 240000 cases at time stamp 3. UK had 120000 cases at time stamp 1, 260000 cases at time stamp 2 and 280000 cases at time stamp 3. The program starts by displaying the following menu: Search by country Search by time stamp View all 1. 2. 3. Input your choice: If the user inputs 1, the program prompts for the country name and displays the information related to this country. For example, if the user inputs "Lebanon", the program displays: Lebanon: 25, 1000, 2000. If the user inputs 2, the program prompts for the time stamp and displays all the number of cases in each country at this time stamp. For example, if the user inputs 2, the program displays: Lebanon: 1000; France: 123000; UK:260000. If the user inputs 3, the program displays all information as follows: Lebanon: 25, 1000, 2000; France: 100000, 123000, 240000; UK: 120000, 260000, 280000. Pay attention: Think carefully about the data structure you want to use to store your information in. Each country appears one in the sequence and associated with each country are its three numbers. The coding part is very easy once you get the right data structure.

Please DO NOT respond to this question by copy/pasting the code provided elsewhere on the site, none of those work. Thanks. Virtual Memory Lab This lab project addresses the implementation of page-replacement algorithms in a demand-paging system. Each process in a demand-paging system has a page table that contains a list of entries. For each logical page of the process, there is an entry in the table that indicates if the page is in memory. If the page is in memory, the memory frame number that page is resident in is indicated. Also, for each page, the time at which the page has arrived in memory, the time at which it has been last referenced, and the number of times the page has been referenced since the page arrived in memory are maintained. The page table data structure is a simple array of page-table entries (PTEs). Each PTE contains five fields as defined below: struct PTE { int is_valid; int frame_number; int arrival_timestamp; int last_access_timestamp; int reference_count; } Each process in the system has a page table that is simply an array of PTEs. Each process also has a pool of frames that is allocated. The frame pool for a process is represented as an array of integers, where each Integer represents the frame number of a frame that is free and is available for use by the process. Note that in order to get the frame number in the pool, you first need to access the integer in the array. This lab project aims to exercise the various policies for page replacement. In particular, we study the following three page-replacement policies: First-In-First-Out (FIFO) Least-Recently-Used (LRU) Least-Frequently-Used (LFU) In order to implement the above policies, we need to develop corresponding functions that process page accesses for a process. That is, for each process, given its page table, a logical page number being referenced and the free frame pool of the process, the functions should determine the memory frame number for the logical page. Also, the functions should modify the page table and the free frame pool appropriately. The details of the functions with respect to the different policies are described below. You need to develop code for these functions that implement the specifications. Place the code in a file called virtual.c. You should include the oslabs.h file.

No calculations are necessary. Think about which ratios would be affected by changes in these two accounts. (10 marks)

In this week’s reading, you learned about one-to-one and many-to-many relationships. While the concepts may seem beneficial, there are some drawbacks. For this discussion, you need to evaluate the pros and cons of each and make a recommendation regarding the usefulness of using these concepts in the JCC RDBMs .
