The main two pits: jquery's serialize () will escape the space to + when the character turns into an object and turn the + sign into a space. For example:Then after executing the serialize () method, the resulting string is 12+34%2b56;That is, jquery's serialization method to escape the space, converted to the + number, "+" number escaped is%2b2. Always think that the key encoding in the serialized string is useless, key must be encoded, if key does not encode the following situati

-sequences inside the sequence of long L.Idea: This problem requires the first introduction of the formula F (L) = f (L-1) + f (L-3) + f (L-4). And then the Fibonacci sequence of the same way, the structure of the matrix, the following is the matrix fast power.Formula derivation:We consider the last character of the L long sequence C1One: C1 = m, we do not have to consider the preceding L-1 character, directly have the scheme number F (L-1);Two: C1 = f, we need to consider the second-to-last cha

Qvariant The pointer data cannot be saved by default because the Qvariant constructor with the void * parameter is private.However, with the meta-type mechanism provided by QT, arbitrary pointers can be stored in the qvariant.You need to register the type with the Q_declare_metatype macro. 123 q_declare_metatype(qstandarditemmodel*) After that, you can use Qvariant::fromvalue to store data and use Qvariant::value to get the data. 12345

This method is a stored procedure. A stored procedure is a set of pre-compiled SQL statements and optional control flow statements. It is stored in a database and can be executed by an application through one call, it also allows users to declare va

NumPy mean (), STD () and other methods are acting on the entire numpy array, if it is a two-dimensional array, but also the entire array, including all the rows and columns, but we often need it only for rows or columns, rather than the entire two-dimensional array, this time, you can define axis axis:axis=0 represents the action on the columnaxis=1 indicates the action on the lineTake the sum () sum method as an example:Import= Np.array ([ [1, 2, 3], [4, 5, 6], [7, 8, 9]]) Print
