Can someone share the solution of both problem on the techgig code gladiator contest? Also do they really give out Rs 500 Amazon voucher?

The first one was simple just simulate the possibilities considering only when the fish enters.

The second one was max-flow. Consider a universal source U. Now add edges U to i with weight as the number of monkeys on tree i(ti).

Let sum of all ti = S.

Now next create nodes 0',1',2',.. which have exactly 1 incoming edge from 0,1,2,... with some infinite weight . The position of 0 and 0' are same , 1 and 1' are same and so on..,

Now from 0' add edges to all original nodes(0,1,2,...) that are reachable from it.

Now perform maxflow from U to 0 , U to 1 ,... and for nodes whose maxflow is S increment the answer.

P.S. Regarding amazon vouchers will let you know if I receive it.

    Can you share your code?

    For the amazon voucher, I think if someone who participated last year could provide information.

Also I don't know why but I don't think these 300 people selected were actually capable of writing max flow. Almost every one of them is in jobs like Jio,Vodafone,Fliplkart,IG Infotech,Wipro,etc and I don't think many of them is present on major programming platforms like CF,CC,Hackerrank so how can they do the complex second problem being in "normal" jobs.

    LOL, what a shit I read. The rest of the comment would be in Captain Obvious mode.

    I see several options, how it may happens:

    1. they could be involved in competitive programming (CP) and gained major experience before they started working;

    2. they do CP in their free time as a hobby;

    3. 1 + 2.

    And, IMHO, you shouldn't think about their successes and look for deception there, but concentrate on your performance and self-development if you want to achieve something.

    Just checked your other posts here — you are really miserable! You asked for help with problems from this tournament while it was in progress and now you suspect of cheating others? Shame on you!
