How does powerdesigner add fields shared in each table: Sometimes there are some common fields when creating a table, but each table is to be created. This is very troublesome, especially when repetitive work occurs. If you do not pay attention to

Problem description: Given an input string, reverse the string word by word. for example, given S =" the sky is blue ", return " blue is sky the ". Solution: The split () method is used to divide a sentence into a list of several words by

Substr (parameter 1, parameter 2 [, parameter 3]);The system function returns the truncated substring. It accepts two required parameters. Parameter 1 is the string to be truncated, parameter 2 is the starting position of the truncation, and

The binary (16-bit) reverse order is required to be calculated. For example, the number 12345 is represented in binary: 00110000 00111001 In reverse order, we get a new binary number: 10011100 00001100 The easiest way to think of it is to exchange
