Chapter 4, Problem 2MD
(World Population Growth) World population has grown considerably over the centuries. Continued growth could eventually challenge the limits of breathable air, drinkable water, arable cropland and other limited resources. There’s evidence that growth has been slowing in recent years and that world population could peak some time this century, then start to decline.
For this exercise, research world population growth issues online. Be sure to investigate various viewpoints. Get estimates for the current world population and its growth rate (the percentage by which it’s likely to increase this year). Write a
The first column should display the year from year 1 to year 75. The second column should display the anticipated world population at the end of that year. The third column should display the numerical increase in the world population that would occur that year. Using your results, determine the year in which the population would be double what it is today, if this year’s growth rate were to persist.

Introductory:
The Caesar Cipher technique is one of the earliest and simplest methods of encryption techniques. It is simply a type of substitution cipher, i.e., each letter of a given text is replaced by a letter some fixed number of positions down the alphabet. For example, with a shift of 1, A would be replaced by B, B would become C, and so on. The method is apparently named after Julius Caesar, who apparently used it to communicate with his officials.
Thus, to cipher a given text we need an integer value, known as a shift which indicates the number of positions each letter of the text has been moved down.
The encryption can be represented using modular arithmetic by first transforming the letters into numbers, according to the scheme, A = 0, B = 1 ,…, Z = 25. Encryption of a letter by a shift n can be described mathematically as.
En(x) = (x+n) mod 26

Earth from you to being directly overhead, by what percentage does (a) the Moon's gravitational pull on you increase and (b) your

- Correct answer will be upvoted else downvoted. Computer science. After painting the white cells of the board, you want to place the maximum number of dominoes on it, according to the following rules: each domino covers two adjacent cells; each cell is covered by at most one domino; if a domino is placed horizontally (it covers two adjacent cells in one of the rows), it should cover only red cells; if a domino is placed vertically (it covers two adjacent cells in one of the columns), it should cover only blue cells. Let the value of the board be the maximum number of dominoes you can place. Calculate the sum of values of the board over all 2w possible ways to paint it. Since it can be huge, print it modulo 998244353. Input The first line contains two integers n and m (1≤n,m≤3⋅105; nm≤3⋅105) — the number of rows and columns, respectively. Then n lines follow, each line contains a string of m characters.

He likes beer so much that has K cups of beer daily. However, having more than K cups doesn't suit him, because the excess beer won't allow him to sleep at night. Danish's working day is divided into N periods. For every period, he knows how many kilobytes of weight he can lift. During each of the periods, Danish can either have or not to have one bottle of beer. If he is having a bottle of beer in some period, the amount of work in this period drops to zero. But he also gets a productivity boost, if he decides to skip beer during a period and the last bottle of beer, he had was no more than D periods ago, the amount of work during such a period is M times the usual.arrow_forwardIn c++.

- Exercise B: Some initial values may make the PageRank algorithm converge faster, you can use a program to try different initial values. You can use a smaller floating number precision (fewer decimal places) to converge faster. Or you can assume if the PageRank values change in less than a certain percentage (e.g., 5%), they are converged.arrow_forwarddef winning_card(cards, trump=None): Playing cards are again represented as tuples of (rank,suit) as in the cardproblems.pylecture example program. In trick taking games such as whist or bridge, four players each play one card from their hand to the trick, committing to their play in clockwise order starting from the player who plays first into the trick. The winner of the trick is determined by the following rules:1. If one or more cards of the trump suit have been played to the trick, the trick is won by the highest ranking trump card, regardless of the other cards played.2. If no trump cards have been played to the trick, the trick is won by the highest card of the suit of the first card played to the trick. Cards of any other suits, regardless of their rank, are powerless to win that trick.3. Ace is the highest card in each suit.Note that the order in which the cards are played to the trick greatly affects the outcome of that trick, since the first card played in the trick…arrow_forwardDO NOT COPY FROM OTHER WEBSITES Correct and detailed answer will be Upvoted else downvoted.

You are not told how many teams are participating but you do know that: Each team has a name, which is one of the uppercase letters A-Z. No two teams have the same name, so there are a maximum number of 26 teams. Each team has the same number of members. No two runners cross the finish line at the same time – i.e. there are no ties. At the end of the race we can write the results as a string of characters indicating the order in which runners crossed the finish line. For example: ZZAZAA We can see there were two teams: A and Z. Team A’s runners finished in 3rd, 5th and 6th place. Team Z’s runners finished in 1st, 2nd and 4th place. Scoring the race Each runner is assigned a score equal to their finishing place. In the example above team Z’s runners achieved scores of 1, 2 and 4. Team A’s runners scores were 3, 5, and 6 respectively. The team’s score is the sum of the members score divided by the number of people on…arrow_forwardProgram Specifications Write a FancyCar class to support basic operations such as drive, add gas, honk horn and start engine. fancy_car.py is provided with function stubs. Follow each step to gradually complete all instance methods. Note: This program is designed for incremental development. Complete each step and submit for grading before starting the next step. Only a portion of tests pass after each step but confirm progress. The main program includes basic calls to the instance methods. Add statements in the main program as instance methods are completed to support development mode testing. **Step 0: Complete the constructor to initialize the model and miles per gallon (MPG) with the values of the parameters. Initialize the odometer to five miles and the tank to be full of gas. By default, the model is initialized to "Old Clunker", and MPG is initialized to 24.0. Note the provided constant variable indicates the gas tank capacity of 14.0 gallons. Step 1 Complete the instance…arrow_forward

The task is to identify a celebrity by only asking questions to people of the form: ”Do you know him/her?” Solution Select two people from the group given, say, A and B, and ask A whether A knows B. If A knows B, remove A from the remaining people who can be a celebrity; if A doesn’t know B, remove B from this group. Solve the problem recursively for the remaining group of people who can be a celebrity Which design strategy does the following solution use?

It has to be turned in on time in order to get participation credit. I'll come into class and go over the solution right away. Then I will collect your work on the exercise. Be ready to turn it in at that time. Fill out the table for the knapsack problem, where the objects, weights, and values are as given, and the overall weight limit is 10. Next, circle the entries in the table that are used when backtracking to find objects to use in the solution. Then list the object numbers that can be used for an optimal solution. Also list the weights and values of those objects. Verify that the values of your solution objects add up to the optimal number in the last row and column in the table. Verify that the sum of the weights of your solution the objects is not more than the overall weight limit of 10. Weight Capacity -----> obj # wt val | 0 1 2 3 4 5 6 7 8 9 10…arrow_forward
