ICOT- the answer to the riddle (in plain english)is:
key- C= Cannibal
W= Whiteman
1C and 1W cross and 1C comes back
2C crosses and 1W comes back
2W crosses and 1C and 1W comes back
2W crosses and 1C comes back
2C crosses and 1C comes back
2C crosses
(the riddle was from before yom tov so here it is again, You have 3 canniballs and 3 whitemen that have to cross a river. They have one boat that can hold 2 ppl.
How is it that they can all get across (don’t forget that s/o has to bring the boat back) but at any time on either side there can’t be more cannibals than whitemen?)
