Another one:
Imagine you have gone to China (from Chandni Chowk, ofcourse) and you have learnt "talwarbaazi" over there. Now you are faced with a dragon and you are supposed to kill it. The dragon has 3 heads and 3 tails. A dragon is considered dead if ALL heads and ALL tails are chopped off. But this dragon is nasty. Here are the conditions:
1) If 1 head is chopped off, 1 extra head grows.
2) If 1 tail is chopped off, 2 extra tails grow.
3) If 2 tails are chopped off together, 1 head grows.
4) If 2 heads are chopped off together, nothing grows.
So what is the minimum number of 'slashes' required to kill the dragon?
this is also preety simple. remember "MINIMUM NUMBER OF SLASHES".
I got the answer.It is damn simple.
1)In First Shot he cut 2 heads together so nothing grows.
Now dragon has 1 head , 3 Tails .
2)next shot he cut 2 tails , so another head grows.
Now 2 heads , 1 tail.
3)He cuts 1 tail so that 2 tails grow.
now 2 heads , 2 tails
4)he cut once again 1 tail so that 2 grows
now 2 heads , 3 tails
5)another 1 tail gone so that 2 tails grow
now 2 heads , 4 Tails
6)He cut 2 tails , 1 head grows
Now 3 heads , 2 tails
7)He cut another 2 tails so 1 head grows
Now 4 head and no Tail
8)He cut 2 heads nothing grows.
Now 2 heads and no tail
9)Again he cut 2 heads and nothing grows.
Now NO HEAD AND NO TAIL!!
