BKJIA comprehensive report] On April 14, Nokia held a network conference called Discover Symbian yesterday, officially announced the previous spy photos of the X7-00 and E6-00. In addition, the PR2.0 system code is Symbian Anna.
Symbian Anna adds a more user-friendly input interface and uses a brand new browser, which is faster. Mobile phones that support updates to Symbian Anna include Nokia C7, Nokia E7, Nokia C6-01, and Nokia N8 are not yet confirm

special background music, you can use the sound will be added, as very simple. The transitions and filter effects are very useful, so you can further refine your pictures or videos. I used a video and image editing software for many years, after several versions of the update, the number of features and library constantly increased, but also let me use more convenient, for my work saved a lot of time and steps. Now I'm more and more in love with this software.Original address: http://www.huis
the FTP server. The server uses TCP port 20th to establish a data connection with the client. Typically, the server actively establishes or interrupts the data connection.FTP transfer ModeFTP transmits data in two modes of transmission: ASCII mode and binary mode.ASCII mode is used to transfer text. The character of the sender is transferred to the ASCII format before it is sent, and the receiving end is then converted to a character. Binary mode is commonly used to send picture files and progr

) +GRXRThe sender uses the specified g (x) to generate the CRC code word, and the receiver verifies the received CRC by the G (X). 4, CRC check Code software generation method:With the help of polynomial division, the remainder is a check field. For example: The Information field code is: 1011001; the corresponding k=6 polynomial m (x) =x6+x4+x3+1 assumes that the resulting polynomial is: g (x) =x4+x3+1; then the code for G (x) is: 11001 x4m (x) =x10+x8+x7
is also not difficult to prove with contradiction: either Z∈lcs (Xm-1, Y), or Z∈lcs (X, Yn-1). Since ZK≠XM and Zk≠yn have at least one of them to be established, if ZK≠XM has Z∈lcs (Xm-1, Y), similarly, Zk≠yn (X, Z∈lcs). At this point, the problem is attributed to Xm-1 and y LCS and X and Yn-1 LCS. The length of the LCS (x, y) is: Max{lcs (Xm-1, y), length of LCS (X, Yn-1)}.

, that is, when reading to 01, then 01 is the lowest address, that is, low address to save low-order, high-address save high-byte order, so this time, is the small end,Conversely, when the char type reads the data is 00, that is, 00 this position is the low address, then this time, the low address to save the high-order, high-address preservation is low-byte order, so this is the big-endian.4.

that we have said before can you understand?The combination of several weights can be weighed, and can be represented by the product of several of these functions:(1+x) (1+X2) (1+X3) (1+x4)= (1+x+x2+x3) (1+x3+x4+x7)=1+x+x2+2x3+2x4+2x5+2x6+2x7+x8+x9+x10 From the above function know: can be weighed from 1 grams to 10 grams, the coefficient is the number of schemes.

Arrays. Sort (files); when using it, pay attention to the description of sort. The comparable interface must be implemented for the comparison type.
Java array sorting arrays. sort, and the usage of the comparator interface sometimes need to sort the elements in the logarithm group. Of course, you can write a proper sorting method by yourself. But since there is an arrays. Sort sorting method in the Java package, why not use it when there are few
