Give you a tree\(n\) Tree of nodes\(1\) reach\(n\) The cost is\(1\) reach\(n\) The length of the shortest path between nodes. Now give it to you\(m\) The group asks you to add an edge weight.\(w\) The maximum value of the cost is not the same as the original graph. Questioning is independent of each other.
\(1\leq n,m\leq 3\times 10^5\)
Solution
Spicy chicken, Lao Yu destroys my youth.
hold\(1\) to\(n\) When the path is extracted, it is obvious that the graph becomes a chain plus some subtrees. Greedy thinking is to find such a group of points to meet.
Its subt...

Machine language: (binary code)
The advantage is: as the bottom language, the highest efficiency is the shortcoming: the development is the most complex and the development efficiency is low.
Assembly language:
The advantages are: high efficiency, disadvantages: complexity and low development efficiency.
High-level language:
Separate compilation and interpretation:
Compilation: high efficiency, installation of compiler, no dependence on language execution, and disadvantage of poor cross platform performance.
Interpretability: the development efficiency is the highest, which can be implemented...
First, service network restart error.
Question Description:

First, refresh windows.
document.location.href=document.location.href;
Two. Close the window.
1、 Close the window without any hints.
<a href="javascript:window.opener=null;window.open('','_self');window.close();">Close < /a>
2、Custom prompt closure
<script language="javascript">
// This script is a generic script for IE6 and IE7.

}
else{}
}

Filter introduction
HBaseFilters provide a very powerful feature to help users improve the efficiency of processing data in their tables.
HBaseTwo of the main data reading functions are get and scan, both of which support direct access to data and access data by specifying start and stop key. You can add more restrictions to the query to reduce the amount of data you get. These restrictions can specify column families, columns, timestamps, and version numbers.
All filters take effect on the server side, called predicate push-down, which ensures that the filtered data is not transmitted to the...
