Now comes China! Prince Xan Chi went to fight a 3-headed, 3-tailed dragon. He has a magic sword that can, in one stroke, chop off either one head, two heads, one tail, or two tails. This dragon is of a type related to the hydra(some Greek connections as well!); if one head is chopped off, a new one grows. In place of one tail, two new tails grow; in place of two tails, one new head grows; if two heads are chopped off, nothing grows(phew...). find how to kill him in lowest number of strokes
options r =----------8,9,10 nd 11
Chop off two heads, chop off two tails, chop off two heads.
chop 2 heads - chop 2 tails - chop 2 heads - chop tail
Isn't he dead with no heads?
naah, he is chinese so it lives on without head
animal ain, in ur answer a tail is remaining
and in ur answre @nphuongsun93 , 1 head is remaining,,, nd ur answer is wrong too @AnimalAin ,, work according to options,,,,( cum on i wont post a question if it ws too easy)
There is no specification in the question that all the tails be gone. Anybody that's ever seen a movie with a dragon in it knows that you kill the heads....
OK, here we go. One tail, one tail, one tail, two tails, two tails two tails, two heads, two heads, two heads. No way for the dragon to come back after that sequence. Nine strokes.
