trailing spaces

The swords in the game Good game effect is necessary, cocos2d in the ccmotionstreak to achieve such a trailing effect. Streak=ccmotionstreak::create (1, N, ccc3 (255, 255, 0), "fire.png"); Streak->setposition (CCP (240,160)); This->addchild (Streak, 5); Update the streak position in the touch event to follow the mouse. BOOL Zdscene::cctouchbegan (Cctouch *ptouch, ccevent *pevent) { streak->setposition (ptouch-> GetLocation ());

stack. The effect of recursive overhead on the program is apparent from the PHP example. However, not all languages support tail recursion, even if the language that supports tail recursion is generally optimized for tail recursion in the compilation phase, such as the optimization of the C language for tail recursion. When you use tail recursion to optimize your code, you must first understand the language's support for tail recursion.In PHP, it is not necessary to use recursion unless it impr

What is the difference between a slash and a trailing slash behind a URL? Publisher: Wuhan Xin Ling seo Service Company Date: 2015-8-3 13:10:03 Source: http://www.lrhold.com/ I do not know whether you have carefully observed that some URLs end with a slash, and some URLs are not followed by a slash. At present, Wuhan SEO contact site More or less there is such a problem, and sometimes in order to do the opt

Original question:Apart from the novice programmers, all others know so you can ' t exactly represent numbers raised to some high power. For example, the C function pow (125456, 455) can is represented in double data type format, and you won ' t get all the Digi TS of the result. However we can get at least some satisfaction if we could know few of the leading and trailing digits. This is the requirement of this problem. InputThe first line of input w

The title requires the first three and the last three digits of the K-side of the output n. After the three-bit solution does not have to say, using the two-way fast to die. The key is how does the top three ask? The title says that n can be represented by a 32-bit signed integer, and K is the maximum of 10 six. So N^k's solution ans is at most 10^ (9*10^6), so we can use a 10-base logarithmic x+y, where x represents the integer part of the logarithm, and Y represents the fractional part of the

Beg n! Number of 0 at the end.Ideas1. Discovering Patterns2*5 will produce 1 0,4*25 will produce 2 0,8*125 will produce 3 0,......The even number contains factor 2, so as long as there is 5,25,125 (5^i) appears, there will be a matching 2^i appear,So the final algorithm is to see how many times N contains 5 power.2. Stupid method, first calculate the n!, and then cycle divided by 10, the number of calculations."Other Code"int trailingzeroes (int n) { int0; while (n) {

Deleting spaces using the regular expression s + in js almost solves this problem. I would like to share with you the examples used in this project. I hope this will be helpful to you. The following two requirements are required in the reply box today: 1. The text content cannot contain all spaces. Use this regular expression/^ s * $/2. Delete consecutive spaces.

Nsstring-stringbytrimmingcharactersinset: It's a method you need to keep in mind. It often passes in Nscharacterset +whitespacecharacterset or +whitespaceandnewlinecharacterset to remove the blank symbol at the ends of the input string. It is important to note that this method removes only the contiguous characters in the specified character set at the beginning and end. This means that if you want to remove the extra space between words, see the next step. Let's say you remove the extra s
