Label:This is not required, but if the table name or field name references a keyword in SQL Server, the database does not recognize whether this is a keyword or a table name (or field name) that must be added.For example, a table named User,user is a keyword in SQL Server, so you have to do this when querying:SELECT * FROM [user]Otherwise you will get an error.Similarly, if the user belongs to a field name, it is also added, asSELECT * from table name WHERE [user]=1Why do SQL Server table names

The question of matching JS brackets is a question of matching brackets on codewars.
Question
To determine whether the brackets {}, [], and () in the string match, consider nesting.
Example:
validBraces("(){}[]") // true validBraces("(}") // false validBraces("[(])") // false validBraces("([{}])") // true

Description Let us define a regular brackets sequence in the following way:
1. Empty sequence is a regular sequence.
2. If S is a regular sequence, then (s) and [s] are both regular sequences.
3. If a and B are regular sequences
Character matching and brackets
The period (.) matches various printed or non-printed characters in the string, except for one character. This exception is the line break (\ n ). The following regular expressions match aac, abc, acc, adc, and so on, as well as a1c, a2c, a-c, and a # c:
/a.c/
To match a string containing a file name, and a period (.) is a component of the input string, add the backslash (\) character before the period in the regular ex
DP:
Boundary Condition: DP [0] [J] = 1
Recursive Formula: DP [I] [J] = sum {DP [I-K] [J] * DP [k-1] [J-1] | 0
I pairs of parentheses depth does not exceed J, can be uniquely expressed as (x) y form, where X and Y can be empty, set X with K-1 pair brackets, then the number of corresponding solutions is DP [I-K] [J] * DP [k-1] [J-1]
