We suggest you pass a small, but very ingenious test. Many Japanese employers use it as an alternative to standard interviews. So, look at the picture: the people on the shore and the raft. Purpose: You must transfer the whole group to the other side. But!..
- The raft carries only two people and does not move idly.
- Children can not drive a raft without adults.
- A man can not leave his sons alone with a woman or send one of them with her. The same rule is true in the opposite respect - with a woman and daughters.
- The offender can not be with any of the company without the escort of the sheriff.
Solution Algorithm
To those who managed - applause! For the most curious and impatient - the algorithm for solving the puzzle:- The sheriff carries the prisoner and leaves the latter alone.
- The sheriff fights one of the boys, takes the prisoner and returns to the company.
- The man moves to shore with his second son, comes back and takes the woman. The father remains on the opposite shore, the mother returns.
- The sheriff sits down with the criminal on the raft, the man goes back. Together with the woman they again cross the river and the woman returns back.
- The mother takes one of the daughters, the sheriff is sent back with the prisoner. Sheriff takes the second daughter and returns for her charges. The test is passed!
