okay, their is a farmer walking with his wolf, sheep and a cabbage
and some point he reaches a river that he wants to cros,
so after a quick search he finds this boat,
the problem is the boat is to small to bring them all three in 1 time acros

so it has to be done 1 by 1
but if he leaves the wolf with the sheep, the wolf is gonna eat the sheep
and leaving the sheep with the cabbage the sheep is gonna eat the cobbage

so how does the farmer gets to the other side without losing any of his stuff
