Chapter 3, Problem 23C
Suppose you are designing a multiplayer game that has n ≥ 1000 players, numbered 1 to n, interacting in an enchanted forest. The winner of this game is the first player who can meet all the other players at least once (ties are allowed). Assuming that there is a method meet(i, j), which is called each time a player i meets a player j (with i ≠ j), describe a way to keep track of the pairs of meeting players and who is the winner.

: Given a list of people with their birth and death years, implement a method tocompute the year with the most number of people alive. You may assume that all people were bornbetween 1900 and 2000 (inclusive). If a person was alive during any portion of that year, they shouldbe included in that year's count. For example, Person (birth= 1908, death= 1909) is included in thecounts for both 1908 and 1909.

An arcade game player wants to climb to the top of the leaderboard and track their ranking. The game uses Dense Ranking, so its leaderboard works like this:
The player with the highest score is ranked number on the leaderboard.
Players who have equal scores receive the same ranking number, and the next player(s) receive the immediately following ranking number.
Example
The ranked players will have ranks , , , and , respectively. If the player's scores are , and , their rankings after each game are , and . Return .
Function Description
Complete the climbingLeaderboard function in the editor below.
climbingLeaderboard has the following parameter(s):
int ranked[n]: the leaderboard scores
int player[m]: the player's scores
Returns
int[m]: the player's rank after each new score
Input Format
The first line contains an integer , the number of players on the leaderboard.The next line contains space-separated integers , the leaderboard scores in decreasing order.The next…
The Fibonacci sequence begins with 0 and then 1 follows. All subsequent values are the sum of the previous two, for example: 0, 1, 1, 2, 3, 5, 8, 13. Complete the fibonacci() method, which has an index, n, as parameter and returns the nth value in the sequence. Any negative index values should return -1.
Ex: If the input is:
7
the output is:
fibonacci(7) is 13
Note: Use a for loop and DO NOT use recursion.
import java.util.Scanner;
public class LabProgram { public static int fibonacci(int n) { /* Type your code here. */ } public static void main(String[] args) { Scanner scnr = new Scanner(System.in); int startNum; startNum = scnr.nextInt(); System.out.println("fibonacci(" + startNum + ") is " + fibonacci(startNum)); }}

As the ball rolls down, it strikes a spike and bursts open to release a number of smaller balls (in our simulated game, the number of smaller balls is a randomly generated integer between 2 and 6, inclusive). As the smaller balls further roll down, when one strikes a spike, that ball and all its sibling balls burst and each generates another set of smaller balls (using the same random number already generated for the first roll). The balls keep rolling downhill and striking spikes and bursting into smaller balls until a golden ball is released by one of the bursts. At this time, the game is over and the player is told how many balls were generated during the last burst (including the golden ball). The game is played by two players at a time and the player who had the lowest number of balls generated on the…arrow_forward
- Create a class with a method. The method has to decide whether a given year is a leap year or not. Note- A year is a leap year if: • It has an extra day i.e. 366 instead of 365. It occurs in every 4 year e.g. 2008, 2012 are leap years. For every 100 years a special rule applies-1900 is not a leap year but 2000 is a leap year. In those cases, we need to check whether it is divisible by 400 or not. > > ClassAssignmentEx2 ©LeapYearDecider javaclassnotes.assignments javaclassnotes.assignments ClassAssignmentEx2() LeapYearDecider() main(String):void A isLeapYear(int):booleanarrow_forwardWrite a method to shuffle a deck of cards.

An N x N unit matrix is a matrix of N rows and N columns where all the diagonal elements are ‘1’s and all the remaining elements are ‘0’s.
