Then Made, minimum cut grow very well, so the split point, can be constructed even with a weight of maximum length decrease between the promoter sequence INF $ $ side, $ f_ {i} = 1 $ points and $ S $. $ f_ {i} = mxf $ $ T $ point and even a weight of $ $ INF side, open between the point of even a weight of $ b_ {i} $ edges. run smallest cut like $ QwQ $

Now consider how to engage the additional attributes $ QwQ $?

No, cushions, and write $ yep $ tomorrow
