Pay attention to recursive termination conditions.

1. Problem Description
How to implement simple and fast reverse placement of a single-chain table. (The time-space complexity should be as low as possible .)
2. Problem Solving
The simplest idea is to traverse the linked list, store it to a temporary array, and use this temporary array to create a new linked list. In this case, the time complexity is temporarily considered O (N), but the space complexity of O (n) is required. Next we will descri
When C ++ placement new is used, the size value is not checked. The passed pointer may point to a memory address of only 3 bytes, and you need to execute the new (chararray) int
It can also be executed successfully.
If the input pointer is null, the return value is also null.
Here we mainly understand
Placementnew only initializes the memory you give. The size is not checked.
So if you initialize the memory at another location on the given pointe
ACL placement rules can be placed in the appropriate location to filter out unnecessary traffic, making the network more efficient. ACL can act as a firewall to filter data packets and remove unnecessary traffic. The location of the ACL determines whether it can effectively reduce unnecessary traffic. For example, the traffic denied by the remote destination should not consume network resources on the path to the destination. Www.2cto.com each ACL sho

Favicon.ico is a website logo, usually displayed in the browser's address bar or on the label, can deepen the customer's impression of the site, in addition, can also display search engine results, improve site awaren
The main problem: There are N cities, to establish a radio station in these n cities, each radio station can only cover 2 neighboring cities, ask at least how many wireless power stations need to buildProblem-Solving ideas: English topic good pit, looked at half a day.This problem is similar to POJ-2446 chessboard.All cities can be divided into two point sets, then the connection between the radio station to represent the coverage of the relationship.Because all cities have to be covered, so acc
figure out the center of the radar where each island can be covered, that is, a circle with a radius of R for the small island, the intersection of the circle and the x-axis: The left intersection is X-SQRT (r*r-y*y); The right intersection is X+SQRT (r*r-y*y), and according to the left intersection, if the left intersection of I points is on the right side of the current radar, a new radar should be installed to update the radar otherwise if the right intersection point of I is also on the lef
When practicing Android, want to put a picture in LinearLayout, make its picture pinned, the expected effect is this: But after the XML code ImageView is written like this, And the effect is like this.Try to thank the method, including change to relativelayout layout, adjust layout_grativity and so on, until you think of ScaleType this method: ScaleType property value is Fitstart, the picture is top-aligned;ScaleType property value is Fitend, the picture is bottom-aligned;
not in the narrative.A little off-topic:There is a property in CSS3:-webkit-text-size-adjust.This property is also forbidden font scaling, the advantage of this property is that you can customize the scope, can be set according to project requirements.It is important to note that the function of this property is to disable the text resizing function of the WebKit kernel browser instead of the page zoom control. The minimum limit for Chinese Chrome browser fonts is 12px. However, due to the abus
