stronger (probably a bit inappropriate), such a problem in not specifying which aspect, more exactly who is which field of case can not answer. in the basketball field of course James Strong, but in the football field is naturally more powerful Messi. But the two have the same point, that is they are fast (new and malloc also have the same point, can dynamically open up memory) , new in C + + than malloc to use more extensive , but there is no new in the C language, which is naturally the situ
I want to Judge $_server[' Request_uri '

I use the following method is not a batch, to help see what is the reason, thank you!
Here's My Code:
$abc=$_SERVER['REQUEST_URI']; if(preg_match("/\/price\/xilie-\d-[abc|nba|cba]\.html/",$abc)){ echo "是"; }else{ echo "不是"; }

Observer mode
Observer pattern: Defines a one-to-many dependency that allows multiple observer objects to simultaneously listen to a single Subject object that notifies all observers when the state changes. When an object changes the need to change other objects at the same time, and he does not know how many objects need to be changed, consider using the Observer pattern.

Given a permutation B of 26 uppercase letters, is there A2 = bEach permutation can be considered a product of several loops. We can think of these loops as a necklace of UVA 10294, and the number in the loop is equivalent to the beads in the necklace.A2 is the equivalent of rotating the necklace between two beads of distance, beads 0, 2, 4 ... form a loop with a total of GCD (n, 2) loops with a length of N/GCD (n, 2) for Each loopSo when the length of a loop is odd, the square is still the origi
