Chapter 4, Problem 4.38MAD
(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 precious resources. There is evidence that growth has been slowing in recent years and that world population could peak sometime this century, then start to decline.
For this exercise, research world population growth issues online. Be sure to investigate viewpoints. Get estimates for the current world population and its growth rate (the percentage by which it is likely to increase this year). Write a

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. The j-th character in the i-th string is * if the j-th cell in the i-th row…
Scenario
As you surely know, due to some astronomical reasons, years may be leap or common. The former
are 366 days long, while the latter are 365 days long.
Since the introduction of the Gregorian calendar (in 1582), the following rule is used to determine the
kind of year:
if the year number isn't divisible by four, it's a common year,
otherwise, if the year number isn't divisible by 100, it's a leap year.
otherwise, if the year number isn't divisible by 400, it's a common year.
otherwise, it's a leap year.

a) In the Hi-Lo game, the player begins with a score of 1000. The player is prompted for the number of points to risk and a second prompt asks the player to choose either High or Low. The player’s choice of either High or Low is compared to random number between 1 and 13, inclusive. If the number is between 1 and 6 inclusive, then it is considered “low”. A number between 8 and 13 inclusive is “high”. The number 7 is neither high nor low, and the player loses the points at risk. If the player had guessed correctly, the points at risk are doubled and added to the total points. For a wrong choice, the player loses the points at risk. Create a HiLo application based on this specification. Application output should look similar to:
b) Modify the application to allow the player to continue until there are 0 points left. At the end of the game, display the number of guesses the user took before running out of points.

- Correct answer only. Code and output screenshot. Nastia has 2 positive integers An and B. She characterizes that: The integer is acceptable in case it is detachable by A⋅B; In any case, the integer is almost acceptable, in case it is detachable by A. For instance, if A=6 and B=4, the integers 24 and 72 are acceptable, the integers 6, 660 and 12 are almost acceptable, the integers 16, 7 are neither acceptable nor almost great. Discover 3 unique positive integers x, y, and z to such an extent that precisely one of them is acceptable and the other 2 are almost acceptable, and x+y=z. Input The main line contains a solitary integer t (1≤t≤10000) — the number of experiments. The primary line of each experiment contains two integers An and B (1≤A≤106, 1≤B≤106) — numbers that Nastia has.

We can calculate BMI from the weight of the person (in pounds) and the height (in inches) of the person. The formula for calculating BMI is: BMI = (weightInPounds 703) divided by (heightInInches squared) In this problem, you will have to create a BMI calculator, i.e., a Java program, that reads the user's weight in pounds and height in inches, then calculates and displays the user's body mass index BMI. Also, display the following information from the US Department of Health) so the user can evaluate his/her BMI: BMI values: Underweight: less than 18.5 Normal: between 18.5 and 24.9 Overweight: between 25 and 29.9 Obese: 30 or greaterarrow_forwardThe profit from the sale of a stock can be calculated as follows: Profit ((NS SP) SC) ((NS PP) PC)where NS is the number of shares, SP is the sale price per share, SC is the sale commission paid, PP is the purchase price per share, and PC is the purchase commission paid. If the calculation yields a positive value, then the sale of the stock resulted in a profit. If the calculation yields a negative number, then the sale resulted in a loss.Write a function that accepts as arguments the number of shares, the purchase price per share, the purchase commission paid, the sale price per share, and the sale commission paid. The function should return the profit (or loss) from the sale of stock.Demonstrate the function in a program that asks the user to enter the necessary data and displays the amount of the profit or loss.arrow_forward

Your program must do the following: Print a table that contains the following information for each month. The number of months that have passed. The number adult rabbit pairs (those over 1 month old). The number of baby rabbits pairs produced this month. The total number of rabbit pairs in the lab.

- In Saudi Arabia, the Kudai Parking Area is a parking lot that is next to the Ajyad Police Station and close to the Power Plant. Kudai is a well-known parking space near Masjid al-Haram. After parking there, you can take a taxi to Masjid al-Haram for 10-15 Riyals for a 10-minute drive. The parking is usually heavily occupied, and the following formula is used to compute the parking lot uțilization: Percentage of Parking Lot Utilized - Number of lots occupied + Total number of lots Write a program that calculates the occupancy rate for each zone of a massive parking lot like Kudai. The program should start by asking for the number of zones in the parking lot. A loop should then iterate once for each zone. During each iteration, the loop should ask the user for the number of lots in the zone and the number of them that are occupied. After all the iterations, the program should display the number of lots the parking has, the number of them that are occupied, the number that is vacant, and…arrow_forwardNote: without (return )any value Without using returnarrow_forwardA year in the modern Gregorian Calendar consists of 365 days. In reality, the earth takes longer to rotate around the sun. To account for the difference in time, every 4 years, a leap year takes place. A leap year is when a year has 366 days: An extra day, February 29th. The requirements for a given year to be a leap year are: The year must be divisible by 4 If the year is a century year (1700, 1800, etc.), the year must be evenly divisible by 400 Some example leap years are 1600, 1712, and 2016. Write a program that takes in a year and determines whether that year is a leap year. Ex: If the input is 1712, the output is: 1712 is a leap year. Ex: If the input is 1913, the output is: 1913 is not a leap year. 1 2 3 4 5 6 7 8 9 10 11 Put("{} is a leap year.".format(i_year)) print("{} is not a leap year.".format(i_year)) inputYear = Get next input What would be the code?arrow_forward
