is greater than or equal to the original string length, the suffix array is obtained;To calculate the order of substrings of length 2, simply sort the two-character pairs . For example, the original string Aaba (the subscript of the following letters represents the position of the letter in the original string)A1=A2=a4 a1a2 must be less than a2b3 The order of substrings of length 2k is required, as long as you know the order of the substrings of le
IdeasUsing tree multiplication method can efficiently find two x, y common ancestor LCA.We set F[X][K] to represent the 2k generation ancestors of XF[x][0] is the parent node of XBecause 2k from the X-to-root node can be seen as 2k-1 step from X to 2k-1 step .So for 1≤k≤logn there is F[x][k]=f[f[x][k-1]][k-1] (similar
compared with the son's right element and then sorted into a parent left or right. In this case, until the respective sort merge completes the last two arrays: the first left and right, and only until their respective order, does not confirm the order of the entire array, or it is necessary to complete the real sort by comparing after the end of the back.

, each directory has 16 subdirectories [0~f], However, it seems that phpsession does not support creating directories, you need to create them in advance.
Another problem is the efficiency of small files, generally our session data is not too large (1~2k), if there are a large number of such 1~2k files on disk, IO efficiency will certainly be poor. Efficiency can be provided by caching memcache and MySQL da
helping those who are also transferred from the window camp and would like to help people who are going from Linux to Windows (such as the Boss's request) and those who are interested in 2.Overall, I think 2 operating systems have strengths. I like the freedom of Linux, open, also like Windows Unified, compatible. Below you will compare the similarities and differences of the next 2 operating systems.BTW: With regard to the operating system version, the Windows kernel has not changed much since
The first answer must be the sum of all the edge weights in a connected block containing an end of the diameter, with a diameter of $ab$, and $a$ and $b$ respectively for the root.First, the tree is split by the longest Lufa, so the contribution of each leaf is the distance from the point at the top of its chain.The leaves are sorted by contribution from large to small, and the $h[x]$ represents the minimum value of the leaf rank in the $x$ subtree.For asking $ (x,k) $, you need to take $

This file will be automatically brushed into the MTD1 after each shutdown. This means two things: 1. Any changes you make directly at/DEV/MTD/MTD1 will be restored after

gradually decrement to a general insertion sort of step 1.The following are the sort animations for the hill sort in various situations:Analysis:1. The key to the hill sort is the determination of the step descending sequence, which is capable of descending to a sequence of 1 steps, and now the known better sequence is:
Shell's sequence: N/2, N/4, ..., 1 (repeatedly divided by 2);

+2 = 2 (3k+2), 6k+3 = 3 (2k+1), 6k+4 = 2 (3k+2) are composite, and then remove 6k itself, Prime numbers greater than or equal to 5 can therefore be represented as 6k+1 and 6k+5 (when x is greater than or equal to 6 o'clock, 6k+5 and 6k-1 can represent the same number).Mathematical proofs
Prime number x is greater than or equal to 5, then it must not be a multiple of 3, nor a multiple of 2.
If a natural number is not a multiple of 3, there
engine, tire rotation of the specific process hidden up.2. virtual function mechanismWhen the subclass and the parent class have similar functionality and are not exactly the same, we want to be able to invoke the subclass's function with the parent class, giving the program greater flexibility. C + + provides a virtual function mechanism for us to solve this problem. When using virtual functions in a class, each class produces a table with pointers to these virtual functions, which is the virt
