Imagine there are N teams competing in a tournament, and that each team plays each of the other teams once. If a tournament were to take place, it should be demonstrated (using an example) that every team would lose to at least one other team in the tournament.
Assume there are n = 2x players in a single elimination tournament with x rounds. How many single elimination tournaments should there be in order for the total number of matches to equal the number of matches in a round robin tournament?
There are 7 balls hidden in a box (3 blue and 4 green). If you first select a green ball and do not replace in the box, what is the probability that the second ball you select from the box will also be green? [Your answer can be written either as a fraction or decimal]

- There are a number of plants in a garden. Each of the plants has been treated with some amount of pesticide. After each day, if any plant has more pesticide than the plant on its left, being weaker than the left one, it dies. You are given the initial values of the pesticide in each of the plants. Determine the number of days after which no plant dies, i.e. the time after which there is no plant with more pesticide content than the plant to its left. Example // pesticide levels Use a -indexed array. On day , plants and die leaving . On day , plant in dies leaving . There is no plant with a higher concentration of pesticide than the one to its left, so plants stop dying after day . Input Format The first line contains an integer , the size of the array .The next line contains space-separated integers .

The warden devises a scheme to determine which prisoner is to be released. He tells the prisoners that he will blindfold them and then paint a red dot or blue dot on each forehead. After he paints the dots, he will remove the blindfolds, and a prisoner should raise his hand if he sees at least one red dot on the other two prisoners. The first prisoner to identify the color of the dot on his own forehead will be release. Of course, the prisoners agree to this. (What do they have to lose?) The warden blindfolds the prisoners, as promised, and then paints a red dot on the foreheads of all three prisoners. He removes the blindfolds and, since each prisoner sees a red dot (in fact two red dots), each prisoner raises his hand. Some time passes when one of the prisoners exclaims, "I know what color my dot is! It's red!" This prisoner is then released. Your problem…arrow_forwardThis problem is taken from the delightful book "Problems for Mathematicians, Young and Old" by Paul R. Halmos. Suppose that 931 tennis players want to play an elimination tournament. That means: they pair up, at random, for each round; if the number of players before the round begins is odd, one of them, chosen at random, sits out that round. The winners of each round, and the odd one who sat it out (if there was an odd one), play in the next round, till, finally, there is only one winner, the champion. What is the total number of matches to be played altogether, in all the rounds of the tournament? Your answer: Hint: This is much simpler than you think. When you see the answer you will say "of course".arrow_forward
- You have opened up a new chain of car washes, with t locations spaced in the city. There are n people registered to come on opening day, and they are all living around the city. You want to tell everyone which location to go to such that: Each person doesn’t drive more than 30 minutes to get to their assigned location. You can assume that you can calculate the transit time. The people are distributed evenly such that each location has n/t people attending on opening day. You can assume n divides equally into t. a) Describe an algorithm that checks if this is possible. Clearly describe what you are checking for to see if this is possible. b) Please briefly justify how you’ve handled the constraints and why your approach is correct. c) If possible, describe how to choose where to send each of the n people.arrow_forwardHelp me with these please.

Every evening at 8:00 p.m., a flight will depart. Everyone can see everyone else's eye colour, but no one knows their own (nor is anyone allowed to tell them). Furthermore, they have no idea how many people have blue eyes, but they do know that at least one person has. How long will it take for the blue-eyed individuals to leave?arrow_forward
- There are N people numbered from 1 to N around a round table. Everyone has a different number in their hands between 1 and N. We start with the first person and count the number in his hand and ask the related person to leave the table. If the number in the card odd, we count clockwise. if it is even, we count counterclockwise. Ensure that all people leave the table. The first person to leave the table is the first person. In the sample scenario, the first integer value in the table_in.txt file indicates the number of people around the table, it is 5. The value of the card in the first person’s hand is written on the next line, it is 3. The value of the second person’s card is written on the next line, it is 1. In the table_out.txt file, print the order of people leaving the table.

How many times need the boat pass from shore to shore?arrow_forwardSuppose you begin with one pair of newborn rabbits. At the end of the third month, and at the end of every month thereafter, they give birth to two pairs of rabbits. Each pair of offspring reproduces according to the same rule. Assume that none of the rabbits dic. Let fn be the number of pairs of rabbits at the end of month n, just after the new pairs have been born. We have f₁ = 1, f2 = 1, and f3 = 3. Which of the following is a recurrence relation for fn? Select one: O A. fn fn_1 + fn_3 O B. fn fn-1 +2fn_2 O C. fn fn-1 +2fn 3 O D. fn = fn-1 + fn_2 + fn_3arrow_forward
- There are 2016 passengers about to board a plane, numbered 1 through 2016 in that order. Each passenger is assigned to a seat equal to his or her own number. However, the first passenger disregards instructions and instead of sitting in seat number 1, chooses and sits down in a randomly chosen seat. Each subsequent passenger acts according to the following scheme: if their assigned seat is available, they will sit there; otherwise, they will pick at random from the remaining available seats and sit there. What is the probability that the 1512th passenger ends up sitting in their assigned seat? A. 1/2016 B. 1/2 C. 5/8 D. 3/4 E.

Our goal is to find the smallest value k such that we can fully cover the three ropes with smaller ropes of lengths 1,2,3,...,k (one rope from each length). For example, as the figure below shows, when n₁ = 5, n₂ 7, and n3 = 9, it is possible to cover all three ropes with smaller ropes of lengths 1, 2, 3, 4, 5, 6, that is, the output should be k = 6. = Devise a dynamic-programming solution that receives the three values of n₁, n2, and n3 and outputs k. It suffices to show Steps 1 and 2 in the DP paradigm in your solution. In Step 1, you must specify the subproblems, and how the value of the optimal solutions for smaller subproblems can be used to describe those of large subproblems. In Step 2, you must write down a recursive formula for the minimum number of operations to reconfigure. Hint: You may assume the value of k is guessed as kg, and solve the decision problem that asks whether ropes of lengths n₁, n2, n3 can be covered by…arrow_forwardWe have 13 items in total.
