Discussion of Problem 1527. Bad Roads

If you have WA @ 10
Posted by 198808xc 10 Oct 2010 09:51
This test could help you.

5 8 1 5
2 200
1 2 1 100 99
2 3 0 0 0
3 2 0 0 0
2 4 0 0 0
4 2 0 0 0
3 4 0 0 0
4 3 0 0 0
4 5 1 100 99

You can draw this graph on paper, and the answer will be obvious. I have this output:
99
3
1 4 8

Good luck.
