1.1.1 Remove Duplicates from Sorted Array题目： Given a sorted array, remove the duplicates in place such that each element appear onlyonceand return the new length. Do not allocate extra space for another array, you must do this in place with constant memory. For example, Given input array A =[1,1,2],Your function should return length =2, and A is now[1,2]. 分析： 时间复杂度 O(n)，空间复杂度 O(1)，因为是排好序的。后一个和前一个比较，相同则不要（

The characters in the material seem to be meditating, and the expression is very quiet. Therefore, when the color palette, color should not be too bright, choose a slightly darker brown or light brown.

() => handle (result )); 2. There is an extreme situation, that is, the network condition is poor, and the request must be sent long enough. Such a request will last for several seconds, assume that the network request is called by the Processing Event of a button pressed on the interface, the interface will be stuck. Here is an easy misunderstanding: I think that the WP7 network is asynchronous, so I can not use multithreading. Most of the time, thi

A few days ago, Neo wrote "Naming design in programming". Here there is another article andProgramNamedArticle, You can look at it from another perspective. 1.-variables should be as informative as possible Good variable:Daysdaterange, flightnumber, carcolor.

The text effect in this tutorial is made up of two major parts. One is the text part, the other is the stereoscopic plane. This combination is more commonly used in font effects. Although the production process is a bit cumbersome, the effect is very cool.Final effect 1, a new 800 * 600 pixel document, background fill green: #2F9F2F, the effect of the following figure.
