patient 13 is cured.Before he leaves he wants to meet each patient.doctor said ok but you cannot meet any patient twice​

Answer 1

RIDDLE TIME

It is given to us that the patient is in room 13 and before going out he wants to meet every other patient who are in other rooms but the condition is that he cannot visit the room of other people twice.

There are total 16 patients (not mentioned in the question as it is incomplete)

Now, there can be two scenarios :-

1. When the person has to go out from room no. 4. (Can go in two ways)
2. When the person can go out from any room.

According to the first scenario, the path of the person will be as under :

• 13-->14-->13-->9-->10-->11-->15-->16-->12-->8-->7-->6-->5-->1-->2-->3-->4
• 13-->9-->13-->14-->10-->11-->15-->16-->12-->8-->7-->6-->5-->1-->2-->3-->4

Now, the condition says that the person cannot enter other person's room twice but he can enter his room twice.

According to the second scenario, the path of the person will be as under :

• 13-->9-->5-->1-->2-->6-->10-->14-->15-->11-->7-->3-->4-->8-->12-->16

Answer 2

Step-by-step explanation:

The solution is that first the patient will enter 14 and then will come back to 13. He then goes to 9 from 13, the towards 10 from 9, then to 11, then to 15, then he goes to 16 and then to 12, from 12 he goes to 8 and the in 7, 6 and 5. From room 5 he enters 1 and then roon 2 and then 3 and finally exits from room 4
