Hi all,
I am working on the vertex problem cover and I am trying out some output using:
http://spojtoolkit.com/test/PT07X
I am a bit puzzled as the following test:
5
1 3
3 4
2 4
2 5
gives out 2, which does not seem to be the correct solution. In fact the correct solution would be 3.
Either 1,2,3 or 1,2,4
Is there any wrong assumption that I am making ?
