1.1 Data Situation review
There are two parts to the forum data:
(1) Historical data of about 56GB, statistics to 2012-05-29. This also shows that before 2012-05-29, the log files were in a file, using the Append write method.
(2) Since 2013-05-30, a daily data file is generated, about 150MB. This also indicates that, from 2013-05-30, the log file is no longer in a file.
Figure 1 shows the recording format of the

Idea: can be greedy, can also shortest way.Greedy writing: Because in the guarantee of legal premise, we choose the interval must be the right end point as far as possible, so we choose a legitimate and right end of the next interval is good (if there is no legitimate output-1 can). Time complexity O (NLOGN) (sort is nlogn, greed is O (n)).#include The shortest way to do this: interval [l,r] means you can go from l-1 to R, then we will l-1 a weight of 1 to the edge to r, and then because the in
Some time ago, I saw a line number cleaning tool on cnblogs, but in the command line mode. I always wanted to create a UI style, so I did it when I had time last night, of course, we need to share it with you...
Several problems encountered when doing this software:
1.How can I remove a row number in an effective way.
The first thing I want to consider is to read each line and then remove the leading and trailing spaces and separate t
There is a color segment with a length of n. There are m colors in total. You need to divide it into several segments, and the cost of each segment is the square of the number of different colors in this segment. Calculate the minimum total cost.
SOL:
First, we noticed that the answer should not exceed n, because we can clearly divide each one into a segment and the answer is N.
Therefore, the total color of each segment cannot exceed SQRT (n ).
Therefore, we maintain the final position of the

Code The parent element float container of the outermost layer is not displayed. This is because the child element is floating and is out of the Document Stream, resulting in the parent element's height being zero.
If you change the code:
Note that there is an additional code to clear the floating. This is a good CSS code habit, but this method adds useless elements. Here is a better way to change the HTML code:
Define the CSS class for "floating

Cleaning temporary tablespace in Oracle
Oracle temporary tablespace is mainly used to query and store some buffer data. Temporary tablespace consumption is mainly caused by sorting the intermediate query results. The main functions of temporary tablespace:
Index create or rebuildOrder by or groupDistinct operationUnion, intersect, or minusSort-merge joinsAnalyze
Restarting the database can release temporary tablespace. If the instance cannot be restar
next set of data is found to be greater than e+1. So X needs +1. But we will find that the chosen interval is not [3,9], it should be [2,10].Code:1#include 2#include 3#include 4#include 5 using namespacestd;6 7 Const intn=25010;8pairint,int>S[n];9 intMain ()Ten { One //freopen ("Test.txt", "R", stdin); A intn,i,t; - while(SCANF ("%d%d", n,t)! =EOF) { - for(i=0; i) thescanf"%d%d",s[i].first,s[i].second); -Sort (s,s+n); - intE=0, b=0, x=0; - BOOLflag=0; +s[n]
only such determination can effectively prevent teaching and rigidity, and draw a better line between the two.
Yan Wen mainly talks about Chen Wen from Engels's anti-dulin theory, not from the Contradiction Theory, in essence, Chen Wen is [subjective or objective] directly targeting the Contradiction Theory of Engels [Far Away] without directly discussing the article of Engels, of course, no matter what the discussion is, it is "normal", just as it is normal for Engels to thoroughly criticize

with swap?Swap means the swap partition, which is usually what we call virtual memory, which is a partition that is partitioned from the hard disk. When the physical memory is not enough, the kernel releases some long-unused programs in the cache (Buffers/cache) and then temporarily puts them into swap, which means that swap is used if the physical memory and buffer memory are not enough.Swap cleanup:Swapoff-a swapon-aNote: This cleanup has a precondition that the free memory must be larger th
