also different. Only 26 lowercase letters.How to solve the problem: we need to understand that there is either a unique letter behind each letter, or not. So as long as the first letter of one of my substrings does not appear in the non-first character of the other substring, then I can use this substring as a non-precursor node. such as: Abc,ab,efg,fgk. Because a does not appear as a non-first character in other substrings, a can be a non-precursor node, and e can also. So all we have to do is

HDU 1285 determines the competition ranking (Topology Sorting template)
It is easy to understand the meaning of the question. The key is to see the following: the matching ranking may not be unique. At this time, the team with a small number must be in the front;
Idea: this is the classic application of topological sorting. You can use the queue to prioritize the queuing of small numbers.
Topological sorting:Topological sorting is a sort of directed a

After learning about Topology Sorting today, I found that this topic is a raw question.
So I tried it again as I thought. I used the queue algorithm, namely, the Kahn algorithm. The complexity o (V + E) was completed and handed in. WA...
So I checked it and handed it over again, or WA...
I thought it was a queue problem. I changed it to stack and WA. Then I gave up STL, knocked on the queue, or WA...
I'm crazy.
It's okay. I got stuck for over an hour.

Simple and simple is true. Those high-end foreign copy topologies are purely self-abuse.There are about four principles for implementing replication:① A master database can have multiple slave Databases② One slave database can only have one master database③ Each slave Database Server ID is globally unique④ Log_slave_updates has the utility of pass-throughThe following is a brief introduction to the Topology Design of several types of replication, thei

predicate method takes two geometries as parameters and returns a Boolean value that indicates whether the geometry has a specified spatial relationship. The spatial relationships it supports are: equal (equals), detach (disjoint), intersect (intersect), phase (touches), cross (crosses), inclusive (within), inclusive (contains), Overwrite/ Covered in (overlaps). The General relational (relate) operator is also supported. Relate can be used to determine the dimension extension of the nine-inters
Common topology of MySQL ReplicationThe replication architecture has the following basic principles:(1) Each slave can have only one master;(2) Each slave can have only one unique server ID;(3) Each master can have many slave instances;(4) If you set log_slave_updates, slave can be the master of other slave, thus spreading master updates.
MySQL does not support multi-master Replication-that is, one slave can have multiple masters. However, through som
