In the desert there is a jail. After rebellion the single guard has been immobilized. He watched helplessly how prisoners left one by one with different speed in different directions. Later he free himself and took a motobike with extra seat. Now he can follow footprints and pick up one prisoner at a time and bring them back to jail. Each prisoner moves with constant individual speed v_i and left the jail at time t_i. In which order the guard should bring the prisoners back in order to minimize the time?

The cook must participate in the presence before each class, i.e. call out the names of the students one by one and indicate which students are present. Each student has a first and last name. To save time, Rajesh only wants to call up students' first names. However, if there are multiple students with the same first name, the Rajesh must call out the full names (first and last names) of all those students. For any student who does not share a first name with any other student, the cook can still only call that student's first name. Help the Rajesh decide for each student whether to call that student's full name or just their first name. Note: Please Answer in java language only. Input 1 1 hasan jaddouh Output hasan

Three guys John, Paul and Peter are on a death row in GA. Governor decided to pardon one of them randomly chosen. He told the name of the pardoned to the gourd. Night before execution, each prisoner is in his own cell and none are  supposed to knowwho will be pardoned.  John asks the guard to give him the name from the other two who will be executed. Guard answers that Peter will be executed. John gets happier - before the guard gave him the name, his probability to survive was 1/3, and now when he knows that either him or Paul will be pardoned, his probability to survive is higher = 1/2. Is it correct? Should John be happy?(Give YOUR EXPLANATION for the probabilities for John to be pardoned))

Phineas goes to school after the lockdown is over and finds out that all his N−1N−1 friends have turned into bullies. So he himself too starts disliking his friends. The teacher Dr Doof wants to distribute MM marks to his NN students (including Phineas). Dr Doof is busy in his experiments and so wants the students to distribute MM marks among themselves such that each student gets a non negative integer marks or gets expelled. So he makes a plan. He makes all of his NN students stand in an line and then the NthNth student is made the leader. The task of the leader is to propose the distribution of MM marks among all the students present. Then a voting is carried out and all present students ( including the leader) can vote either for or against the distribution. If the distribution is voted for by at least 50%50% of the students present, then it is is approved with the leader becoming the deciding student and the process ends. Otherwise the last KK present students are expelled (…

Can someone help me understand this problem from my textbook?

Suppose you are provided an even number of people going on an adventure, and there are only two-seated rafts. All rafts are identical, weighing 20kg each. Each person is described by two parameters, their strength and weight. The speed of a raft can be calculated as the sum of strengths of both persons sitting in it, divided by the total weight of the loaded. We would like to choose the allocation of people to rafts so as to maximize the speed at which the whole group can travel, assuming that the group travels at the speed of the slowest raft in it. Develop a python code to find the maximum speed of the group which can be achieved by optimally choosing places for each person. Sample Input: 4 50 50 50 60 70 100 100 60 Sample Output: 0.8421052590012552

For part a how is this right? Say we have a case of these 4 numbers pushed sequentially, 1, 7, 9, and 11. The k-last behavior will not be correct.
