Hello , I'm interested in finding some problems on CodeForces that is related to :
1 — Finding Bridges.
2 — Bellman Ford.
3 — Strongly Connected Components.
4 — Finding Articulation Points.
5 — Spanning Trees.
6 — Finding a negative Cycle in a graph.
Since the only tag that is specified for all of the mentioned points and many others is only "Graphs" so It is hard somehow to find a problem that is related to these points so if someone already knows some , it will be appreciated Thank you :)
Hello I was trying to solve this problem :
http://codeforces.com/contest/3/problem/B
and I could solve it by changing every 2 of size 1 to 1 of size 2 after sorting them and then take the best over all but after that I have been thinking what would be the solution if we have 2 types of sizes 3 and 4 any suggestions ? Thank you.
