correlations do rank in the top k), or the most relevant K-documents that ultimately return the worst relevance sort did not exceed 110%*k.Answer: As the tip says, you can have each machine return the most relevant K ' documents, and then use the idea of merge sorting to get the most relevant k in all documents. The best case is that the K documents are evenly distributed across all machines, when each machine is just k ' = k/n (n is the total number of machines); Worst case, all the most relev
[Code sea shell JS] JS: delete elements in the array, sea shell jsPreface
To delete an element from a list in Java, you can simply use the remove Method.
The array in js does not have the remove method, but in js, the array has the splice method to achieve the same effect. In addition, you can also use other methods to achieve this effect.
Use the splice method to delete
benefit of this encoding method is that the index string is a small, fixed-time operation of the code . Getting the nth code point of a string simply simply selects the nth 16-bit element of the array. The following example: This string, in which each character consists of a code point in the original 16-bit range. for Unicode strings,
First look at the concept of the DOM is a tree, its root node is document, can be roughly shown in the following figure:
The so-called "most recent common ancestor element" refers to a given set of elements that find the most depth in the tree, but also the elements of the ancestor elements of all of these elements.
, the elements in this array are inserted into the specified position.
If the function does not delete any elements (length=0), the alternate array is inserted from the position of the start parameter.
Example 1:
Copy CodeThe code is as follows:
$a 1=array (0=> "Dog",1=> "Cat",2=> "Horse",3=> "Bird");
$a 2=array (0=> "Tiger",1=> "Lion");
Array_splice ($a 1,0,2,
This time to bring you a pure CSS3 code implementation of a number of elements in turn, the pure CSS3 code to implement a number of elements in turn to show the attention of the matter, the following is the actual case, together to see.

: The removed element is substituted by the element in this array. If no value is removed, the elements in this array are inserted at the specified location.
If the function does not delete any elements (length=0), the alternate array is inserted from the position of the start parameter.

You are not mistaken: A label is used to wrap block-level elements. Before HTML5, a label belongs to the intra-row elements, while div, h1, and p are block-level elements. If A label is forcibly wrapped, may be forcibly truncated into multiple a tags. Interested friends can learn more. In comparison to XHTML, HTML5 has caused a series of ideas through simpler

The constructor property always points to the constructor that creates the
Deletes the implementation code of repeated elements in the PHP array.
The previous article describes how to delete the header, tail, and arbitrary elements in the PHP array. This article describes how to delete repeated elements in the array using the array_unique () function.
array_unique()Function, sorts the values
Often we want to delete some elements in the collection. Some might write that.
Copy Code code as follows:
public void operate (List list) {
for (Iterator it = List.iterator (); It.hasnext ();) {
String str = (string) it.next ();
if (Str.equals ("Chengang")) {
List.remove (str);
}
}
}
This type of writing will report the fo
