OJ Board

because 3 isnt reliable and 2 isnt reliable ,so only 1 is reliable so ans is 1,its so simple problem,try all the I/Os in the board, :D :lol: 8)

I think that the problem says that when an informant is not reliable, their words can be true or false, so I don't se a way of how 2 is not relieabe.
Did ...

As an example, let's assume there are four informants A, B, C and D, with the following surveyed answers: ``A says B is reliable but D is not'', ``B says C is not reliable'', and ``C says A and D are reliable''. In this case, it happens that at most two informants are reliable.

Can you tell me ...

Hi, how and imput like this should be treated.

6 4
1 2
2 -3
1 4
4 -2


Would the answer be 5 or 4?

I mean that if we have to look for all transitive relations? and if we have to, on some special cases, wouldn't it take us to an endless loop?

Thanks.
