In the garden, csdn-Chinese is the most discussed in the past two days.It communityThe spread of 6 million user data on the Internet, as a technician, has put aside their own ideas for the moment. From a technical perspective, we can analyze and test our programming basics. Release the downloaded compressed file to the hard disk to obtain the file www.csdn.net. SQL. As a technician, I am curious about this file and have an impulse to program it. The

and return the temporary array. Array.prototype.unique1 = function () {var res = [This[0]];for (var i = 1; i if (Res.indexof (this[i]) = =-1) {Res.push (This[i]);}}return res;}arr = [3,5,2,3,2,2,3,7];Console.log (Arr.unique1 ()); The second method is to create a new hash table and a temporary array, traverse the current array, see if there is a JSON object I , there, skip, none, then let the hash table in the value of the I key attribute is true, and push the value into the tempo

BlockThe problem is relatively simple, and the positive solution is the difference sequence. There are three lines of learning God, recorded as follows:for (int i=1;i{cin>>h[i];if (H[i]>h[i-1]) sum+=h[i]-h[i-1];}My personal approach is the same as the method of learning God, only to say that he is asking for a big reduction, I beg small to reduce the size of theIdeasIt is known that the required cumulative number is subtracted from the public part by the maximum value of the public part + each s

When using SQL Server, it is unavoidable to deal with XML parameters, XML most of the time it is convenient for our program, but there are times when variable assignment does not pass. (Of course, if you have XML that doesn't pass the check of software like the XML Spy, that's not the scope of it.)The example of sharing today is very simple, just test a few examplesDECLARE @xXML--1SELECT @x =''--2SELECT @x =''--3SELECT @x =N''--4SELECT @x =''--5SELECT

, and the point $p$ on each plane is the orbit obtained by the group $g$ (that is, the point set $\{g (p) |g\in g\}$) If there are no points on the plane. Try to prove that $g$ can be generated by one or two translation transformations, i.e. $g=\{n\alpha|n\in\mathbb z\}$ or $g=\{n\alpha+m\beta|n,m\in\mathbb z\}$, where $\MATHBB Z $ is an integer set, $n, m$ is any integer, and $\alpha,\beta$ is a linear-independent translation vector (which also represents its corresponding translation transform
