आशानगरी का युवराज और राक्षस... (The crown-prince and the monster)

विशेष नोट : अगर आप जवाब ढूंढ लेते हैं तो ठीक, वरना कमेंट लिख दीजिएगा, मैं जवाब आपको मेल के जरिये भेज दूंगा...

आशानगरी के युवराज जंगल में शिकार खेलने गए, और अचानक उनके सामने तीन सिर और तीन पूंछ वाला एक राक्षस आ गया...

अब युवराज के लिए आगे बढ़ने या वापस भागने के लिए भी राक्षस से लड़ना ज़रूरी था...

युवराज के पास एक जादुई तलवार है, जो एक वार में एक सिर, दो सिर, एक पूंछ या दो पूंछ काट सकती है...

दूसरी ओर, राक्षस को भी वरदान मिला है कि यदि एक वार में उसका एक सिर काटा गया, एक नया सिर उग जाएगा; एक वार में एक पूंछ काटी गई, दो नई पूंछें उग जाएंगी; एक वार में दो पूंछ काटी गईं, एक सिर उग जाएगा; और यदि एक वार में दो सिर काटे गए, कुछ नहीं उगेगा...

और हां, सारे सिर और पूंछ कटने तक राक्षस मारा नहीं जा सकता...

सो, अब आप लोग मुझे बताइए, युवराज को राक्षस पर तलवार से कम से कम कितने वार करने पड़ेंगे, ताकि उसके सारे सिर और सारी पूंछ कट जाएं, और वह मारा जाए...

Now, the same riddle in English...

Special Note: If you succeed in solving this one, well and good; but in case, you don't, just leave a comment, and I will mail the answer to you...

The crown-prince of Ashanagri goes to a forest on hunting, and one fine day, a three-headed, three-tailed monster halts his way...

Now, he has to fight the monster to move ahead, or even to come back...

The crown-prince has a magical sword that can, in one stroke, chop off either one head, two heads, one tail, or two tails...

On the other hand, the monster has a boon; that is, if one head is chopped off, a new head grows; if one tail is chopped off, two new tails grow; if two tails are chopped off, one new head grows; if two heads are chopped off, nothing grows...

And yes, he can not be killed until all the heads and tails are chopped off...

Now, you guys tell me, what is the smallest number of strokes required to chop off all the heads and all the tails of the monster, thus killing it...?

  2. जवाब सही नहीं है, दीपक भाई... जब चौथे वार में युवराज दो पूंछ काटेगा, तो एक पूंछ और पांच सिर बचेंगे, और आगे का हिसाब-किताब गड़बड़ा जाएगा... फिर से कोशिश करो, भाई... शुभकामनाएं...

  8. waise ye bhi ho sakta hai :

    4 strokes:
    1) Cut 2 heads - 1 head and 3 tails remain
    2) Cut 2 tails - 2 heads and 1 tail remains
    3) Cut 2 heads - 1 tail remain
    4) Cut 1 tail - Dragon dies at the cut so no chance of tail growing back..

  10. cut 2 head - 1 head and 3 tail remain
    cut 1 tail 1 head and 4 tail remain
    cut 2 tail - 2 head and 2 tail
    cut 2 tail - 3 heads only
    cut 2 head - 1 head remain
    cut 1 head - 2 head
    then cut 2 heads and finish
    means 7 bar me wo mara jayega
