River crossing by 3 cannibals and 3 humans
There are three cannibals and three humans need to cross the river, and there is only one boat. There can be only two people at a time while crossing the river. If the number of cannibals become more than number of humans in the bank of the river then they will eat the human. How should they cross the river?

What about the following solution:
ReplyDelete1) HHHCCC -> --
2) HHCC -> HC
3) CC -> HHHC
4) -- -> HHHCCC
How will the boat come back to take the next two?
