Problem description: There are 5 pirates divided into 100 diamonds.

Pirates 1-2-3-4-5 are in order, and the pirates start to propose a distribution plan first, and if the distribution plan is approved by a majority, OK, it will be divided according to this point, if not, then the pirate who proposed the plan will be thrown into the sea to feed the sharks.

The premise is that pirates are extremely intelligent and sensible people. The pirate's proposal must be the best for himself.

Analysis: Backward method:

If there are only 2 people left, no matter what plan the fourth person proposes, as long as he agrees, the plan will be approved by half of the people, so the fourth person can swallow all the diamonds alone;

In order to avoid the situation where there are only 2 people left and the 5th worker does not get a diamond, as long as the 3rd person offers to give the 5th person a diamond, the 5th person will definitely agree, so when there are 3 people left, the distribution of diamonds is 99 0 1;

In order to avoid that when there are 3 people left, the 4th person will not receive any grains, as long as the second person gives the fourth person a diamond, the fourth person will agree, so when there are 4 people left, the diamond distribution is 99 0 1 0;

In order to avoid that when there are 4 people left, the 3rd person and the 5th person will not receive any grains, as long as the first person gives the 3rd person and the 5th person a diamond, the 3rd person and the 5th person will agree, so when there are 5 people left, the diamond distribution is 98 0 1 0 1

You can only press the door button as soon as the door closes (it won't work if the elevator is already going up) and escape from the second floor. There should be no other keys in the elevator to stop the elevator or not stop on the 3rd floor, or stop on the 3rd floor and do not open the door.

The elevator has an emergency device, a power outage or something like that.

Stay in the elevator and don't go out, keep going up.
