Concept explainers
(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.

- Broken Cabins Problem Statement: There is an Office consisting of m cabins enumerated from 1 to m. Each cabin is 1 meter long. Sadly, some cabins are broken and need to be repaired. You have an infinitely long repair tape. You want to cut some pieces from the tape and use them to cover all of the broken cabins. To be precise, a piece of tape of integer length t placed at some positions will cover segments 5,5+1-sit-1. You are allowed to cover non-broken cabins, it is also possible that some pieces of tape will overlap. Time is money, so you want to cut at most k continuous pieces of tape to cover all the broken cabins. What is the minimum total length of these pieces? Input Format The first line contains three integers n,m and k(1sns10°, namsloº, Isksn) - the number of broken cabins, the length of the stick and the maximum number of pieces you can use The second line contains n integers bl,b2,bn (Isbism) - the positions of the broken cabins. These integers are given in increasing…arrow_forwardCorrect code answer with output screenshot. Else downvoted. William is facilitating a get-together for n of his broker companions. They began a conversation on different monetary forms they exchange, however there's an issue: not all of his dealer companions like each cash. They like a few monetary standards, yet not others. For each William's companion I it is known whether he enjoys money j. There are m monetary standards altogether. It is likewise realized that a merchant dislike more than p monetary forms. Since companions need to have some normal subject for conversations they need to track down the biggest via cardinality (perhaps vacant) subset of monetary standards, with the end goal that there are essentially ⌈n2⌉ companions (gathered together) who like every money in this subset. Input The primary line contains three integers n,m and p (1≤n≤2⋅105,1≤p≤m≤60,1≤p≤15), which is the number of broker companions, the number of monetary forms, the greatest number of…arrow_forward(Python matplotlib or seaborn) CPU Usage We have the hourly average CPU usage for a worker's computer over the course of a week. Each row of data represents a day of the week starting with Monday. Each column of data is an hour in the day starting with 0 being midnight. Create a chart that shows the CPU usage over the week. You should be able to answer the following questions using the chart: When does the worker typically take lunch? Did the worker do work on the weekend?

- [Fish Tank] You play with a clown fish that has an initial size so. The fish can eat other fish in a tank organized in m columns and n rows. The fish at column i and row j has a positive size si,j. When your fish eats another fish, it grows by that amount. For example, if your clown fish has a size of 10 and eats a fish of size 5, it becomes of size 15. You cannot eat a fish that is bigger than your size. The game starts by eating any fish in the first (left-most) column that is not bigger than yours. After that, you advance one column at a time by moving right. You have only three allowed moves. You either stay at the same row, move one row higher or one row lower. You will always move to the right. Thus, you will make exactly m moves to advance from left to right. Your goal is to exit the fish tank from the right with the biggest possible size. The figure below shows an example with the best answer highlighted. In this case, the final fish size is 71 (10+8+7+24+22).

- Q3: Interplanetary Spaceflight Milan Tusk is the richest person in the universe. After devoting decades of his life to further our space exploration technologies, he’s finally ready to retire. Being a space enthusiast, the first thing he wants to do is visit n planets p1, p2, …, pn, in this order. He’s currently on planet p0. Milan knows that the distance between planets pi and pi + 1 (for 0 ≤ i < n) is d[i]light years. His spaceship uses 1 tonne of fossil fuels per light year. He starts with a full tank and can fill up his tank at any of the n planets (but he must not run out in between two planets). There’s a huge cost to set up the spaceship for refuelling. Due to financial constraints (he’s not THAT rich), he can fill up his tank at most ktimes. In order to save money and make his spaceship lighter, Milan is looking for the smallest possible fuel tank that enables him to complete his space travel and reach planet pn. What is the smallest tank capacity that enables him to do so?…arrow_forwardTranscribed Image Text 7-a) Danish works as a constructor. Like all constructors, he is also a beer fan. 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_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

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_forward
