The difference between MySQL int (3) and int (11)Note: M here is not a specific length stored in the database, it was always mistaken for int (3) to store only 3-length numbers, and int (11) would store 11-length numbers, which is a big mistake.Summing up, int (m) Zerofill, plus Zerofill after M to show a little bit of effect, such as int (3) Zerofill, you inserted into the database is 10, then the actual insert is 010, that is, add a 0 in front. if i

Nine Chapters count judges Net-original websitehttp://www.jiuzhang.com/problem/31/TopicsGiven an array, two disjoint and contiguous sub-arrays A and B (positional continuous), satisfying |sum (A)-sum (B) | maximum (and the absolute value of the difference). For example [2,-1,-2, 1,-4, 2, 8], can be obtained a=[-1,-2, 1,-4], b=[2, 8], the maximum difference is 16.AnswerThe answer is to preprocess the maximum

The difference between pointers to different types is that the pointer type knows what the compiler interprets in memory content and size in a particular address (the address the pointer points to), whereas the void* pointer represents only one memory address, and the compiler cannot pass the pointer to the object's type and size, so you want to pass void* The pointer manipulation object must be type-converted. ★ Same point: 1. Is the concept of an a

Windows7 flagship 64-bit and 32-bit difference At present, we are using the WIN7 system, if it is greater than 4GB memory installed users need to pay attention to the system is the number of cases. If the user is greater than 4GB memory, the Windows7 64-bit system should be installed. However, the data width of CPU GPRs (general-purpose registers, universal Register) is up to 64 bits. If the dual-core CPU can be installed 64-bit system. Conversely,

First flock and Fcntl are system calls, and LOCKF are library functions. LOCKF is actually a fcntl package, so the LOCKF and Fcntl are the same, and the effect of locking the file is the same. The Fcntl and LOCKF are put together in most cases when the analysis is different. The next step is to look at the use of each function, from the way it is used and the effect of each function to see the difference. 1. Flock Function prototypes int flock (int

The core of LABJS is LAB (Loading and Blocking): Loading refers to asynchronous parallel loading, Blocking refers to synchronous waiting for execution. Labjs through elegant grammar (script and wait) to achieve these two characteristics, the core value is performance optimization. LABJS is a file loader. Second, Requirejs and SEAJS are modular loaders, advocating a modular development philosophy, the core value is to make JAVASCRIPT modular development become simpler and more natural. The modul
