Code:
#include
Ultraviolet A 11504-Dominos (strongly connected component)
High-connectivity components of the uva-1 11504 Dominos
Q: If a domino card has an edge u-> v, it means that u has fallen v automatically. The minimum number of manual push requests is required.
If some cards belong to the same strongly connected component, if any card is pushed down, all cards are pushed down. After the point can be scaled down through strong connectivity, there must be no card of entry level.
