- Consider the following scenario:A high school has 1000 students and 1000 lockers, one locker for each student. On the first day of school, the principal plays the following game: She asks the first student to open all the lockers. She then asks the second student to close all the even-numbered lockers. The third student is asked to check every third locker. If it is open, the student closes it; if it is closed, thestudent opens it. The fourth student is asked to check every fourth locker. If it is open, the student closes it; if it is closed, the student opens it. The remaining students continue this game. In general, the nth student checks every nth locker. If it is open, the student closes it; if it is closed, the student opens it. After all the students have taken turns, some of the lockers are open and some are closed. The program see in the photo, when ran, should ask the user to enter the number of lockers in the school. The program will output the number of lockers and the…In a prison, there is a door b/w any pair of adjacent cells and one exit guarded by a guard G. One prisoner is a maniac M which kills anybody he can see when he enters a cell. If M returns to the cell with his victim, then he loses consciousness and stops. In the evening all inmates and the guard went to sleep in their cells. In the morning, maniac M is gone and all other prisoners with the guard were found dead in their cells. Show the route of the maniac.Three persons P1, P2, and P3 were invited by their friend F to make some smørbrød (sandwich made of bread, eggs, and tomato) together. To make a portion of smørbrød, three ingredients are needed: a slice of bread, a slice of tomato, and a slice of an egg. Each of these persons P1, P2, P3 has only one type of each of the ingredients: person P1 has slices of bread person P2 has slices of tomato; person P3 has slices of egg. We assume that persons P1, P2, and P3 each has an unlimited supply of these ingredients (i.e., slices of bread, slices of tomato, slices of egg), respectively. Their friend F, who invited them, also has an unlimited supply of all the ingredients. Here is what happens: the host F puts two random ingredients on the table. Then the invited person who has the third ingredient picks up these other two ingredients, and makes the smørbrød (i.e., takes a slice of bread, puts on it a slice of tomato, and puts on top a slice of egg), and then eats the smørbrød. The host of…
- Correct answer will be upvoted else downvoted. Computer science. lamp can be coordinated to enlighten either a few lights to the left or a few lamps to the right. In the event that the I-th lamp is gone to one side, it enlightens all such lights j that j∈[i−pi,i−1]. Also, in case it is gone to one side, it enlightens all such lamps j that j∈[i+1,i+pi]. You will probably pick a course for every light so every lamp is enlightened by undoubtedly another lamp, or report that it is incomprehensible. Input The primary line contains one integer t (1≤t≤10000) — the number of experiments. Each experiment comprises of two lines. The primary line contains one integer n (2≤n≤3⋅105) — the number of lamps. The subsequent line contains n integers p1,p2,… ,pn (0≤pi≤n) — the force of the I-th lamp. The amount of n over all experiments doesn't surpass 3⋅105. Output For each experiment, print the appropriate response as follows: In case it is feasible to coordinate all lamps…There are three groups of people who like Popcorn, Candy, and Soda. 12 people like Popcorn, 11 people like Candy, 10 people like Soda. 5 people like Popcorn AND Candy, 6 people like Candy AND Soda, and 3 people like Popcorn AND Soda. Only 2 people like ALL THREE. So how many people like Popcorn or Candy (or both) BUT NOT Soda?Three prisoners have been sentenced to long terms in prison, but due to over crowed conditions, one prisoner must be released. 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…
- 1- If the rat ate the cheese or the rat is not in the trap, then it is under the bed. The Rat is neither under the bed nor under the table. You will see the Rat Footprint unless It is under the table, or it is not in the trap. The Rat drinks the water if you see its footprint. The rat ate the cheese, or it did not eat the newspaper. Therefore, if the rat neither under the table nor under the bed, then it did not eat the newspaper but it drank the water. a. Covert the above argument into symbolic. b. Show that the argument is valid.Consider the following scenario: A high school has 1000 students and 1000 lockers, one locker for each student.
