has multiple source points, multiple sinks, and several common points.Only the source and sink points are marked with X/y, the normal point is not marked X/y, and all the edges given are X/Y. This is undoubtedly prompting us to make a variant of the diagram: suggest a super source S. A super sink T, so that s point to all source points, and the source point capacity y as the capacity of these edges, so that all sinks point to T, and the capacity of the sink point y as the capacity of these edge
