In the project application, there was a scenario:interface requires sending an int type of serial number, due to multithreading mode, if the timestamp, there may be duplication (of course, the probability is very small).So think of the use of an

SQLiteYou cannot create custom functions directly, not asSQL Servereasy to create and use. But we can still create it, and once we create it, we can do whatever we want (likebatch updates, etc.)A sequence is a very common operation in a database,

Code:x = [1, 1, 1, 1, zeros (1,4)]; N = 8; % zero-padding Operation x_dft = DFT (x,n); % DFT of x (n) magx_dft = ABS (X_DFT) phax_dft = Angle (x_dft) *180/pi%

Missile interception is a classic problem: finding the longest non-ascending subsequence of a sequence, and finding that it can be divided into at least several non-ascending subsequences. The first question is classic dynamic planning. The second
