Can anyone give me some help
By Seals, 13 years ago, In English

I have trouble with this problem:

I thought it is the same as this problem:

I thought it is a maximum closure problem and I solved it using network flows, but I failed on the first one. Can anyone tell me why or give me some hints?

    I know it is a maximum closure problem actually, however, I got WA, and I want to find out why it's not correct.
