I began to use the record path, found no solution, engage in a day, and then Baidu a puzzle.

The first Chinese Question of poj.
At the beginning, the algorithm was wrong.
Algorithm with the initial error:
1. Create a Graph Based on the question
2. Floyd evaluate the passing closure.
3. Calculate the dijsktra algorithm once starting from 1 and record its path
4. enumerate the points that can be reached by 1, find the minimum straight, and determine whether the points on the path meet the level limit.
After the
phpmyadmin.
The above operations are performed in phpmyadmin.
First, add the id. If you select unique, you cannot add the id. You can leave it empty.Changing int to bigint is also invalid.
If you select to be empty, the field can be added, but the data cannot be added under the field. For example, if you add 2, it is repeated.
If you select the primary when adding a field, you cannot add it anyway.
In fact, there are only two fields in my table. One username is a character, and the other pas
Thought: This is the transformation of the Dijkstra algorithm. To solve this problem, I personally think it is necessary to deeply understand the concept of this algorithm. Why? That is to make you understand algorithm templates more deeply based on your thinking (for personal opinions, Do not spray 2333333 if you are wrong)
So for this question, you can write each number in the draft, and you will find that you can create a graph and write its replacement position from the first position, we ca
I just learned that PHP and MySQL were having trouble adding fields when using phpMyAdmin.
The above is the operation in the phpMyAdmin
The first is to add the ID, select unique can not add, at this time there is no check to empty.The online said to change int to bigint also invalid.
If you choose to be empty, the field can be added, but you cannot add data under the field, such as adding a 2 to repeat.
If you select Primary when you add a field, you cannot add it anyway.
In fact, I only have
PhenomenonWhen we encode the implementation to request a page, the requested code resembles the following code:HttpWebRequest req = (HttpWebRequest) webrequest.create (strURL);Req. useragent = "MSIE6.0";Req.

The exchange value between an item and another item can be seen as the Benquan of the two items, the need to pay attention to is the level of restrictions, the beginning did not see the point of view, that is as long as two people's level limit of
At first glance, this question seems very simple. Then I think u, v, and w cannot win if they are all smaller than others. Otherwise, they will win, however, this approach is half the same.
The conclusion that win is not true, but win's conclusion
I can't say anything about this question. I have been crazy about it for a long time. Now I am finally AC. I have spent too much time on this question ,,,,When I first read this question, I thought of using DFS. Later I remembered that I had read
DijkstraAlgorithm: Directed graph G = (V, E)
1. Put the Source Vertex V0 into the set S, and the counter C = 0. Each node has a structure data D (A, B). A indicates the shortest path length to v0, and B indicates the frontend node of. Initialize V0
I won't talk about the meaning of the Chinese Question. Note that the class gap between all people cannot exceed one value, not between two people. (the wrong question is wa for half a day ),
After creating a graph, you can obtain the minimum
