Algorithm general description:
Regular expression a: concept of computer science.Regular expression, which is usually used to retrieval, replaces those meets
The text of some mode (rule).
This algorithm carries out abbreviation to complicated expression formula using regular expression technology
1. defining the regular expression RegexA that two operands (or counting and variable) are multiplied
2. the regular expression RegexB that definition matches a real number
3. pair expression formula (being denoted as ExpressionA) matches, the word that a rule meets regular expression RegexA is matched
String is accorded with, obtains a value type to character string (expression formula that two numbers or number are multiplied with variable) the progress operation come is matched
As a result.The value type result is replaced into the character string that RegexA is matched in ExpressionA, is often done so primary such
Abbreviation, the multiplication sign (*) in expression formula will lack one
4. repeat upper step, until, without multiplication sign (*), at this time remaining expression formula is denoted as ExpressionB in expression formula,
ExpressionB contains only+or-operator
5. couple ExpressionB is matched according to RegexB, real number all in expression formula (such as expression formula is matched
For " -40-6-4+2.1-91 ", -40, -6, -4 ,+2.1, -91 five real numbers can be matched using RegexB), real number is carried out
Being added and obtaining the regular expression of multiplying in result matching expression is that (Java language description) uses constant
RegexA is indicated
String
RegexA=" (d) (*) ([) (d+) () ((?: [a-z] [a-z]+)) (]) "；
This step purpose is that all multiplication operation expressions are matched using RegexA, carries out abbreviation, is finally obtained only
The expression formula of remaining "+" and "-" operator, is described in detail by taking 2* [600837.SS] -3* [000783.SZ] as an example:
The value for expression formula 2* [the 600837.SS] -3* [000783.SZ] for needing to ask stores the word using temporary variable S3
Symbol string, i.e.,
String S3=2* [600837.SS] -3* [000783.SZ]
Traversal expressions S3 matches 2* [600837.SS] using regular expression RegexA, is put into temporary variable S1
S1=2* [600837.SS]
S3=S1-3* [000783.SZ]
[600837.SS] replaced in S1 is real price 8 (member), calculates the value of S1
S1=2*8=16
S3=16-3* [000783.SZ]
Continue traversal expressions S3, matches 3* [000783.SZ] using regular expression RegexA, be put into temporary variable
S2
S2=3* [000783.SZ]
S3=16-S2
[000783.SZ] replaced in S2 is real price 4.9 (member), calculates the value of S2
S2=3*4.9=14.7
S3=16-14.7
Only it is left+- operator in S3 now
Define regular expression String RegexB=" ((?≤ (|-| +)-? d+) | (^- [0-9]+) "；
S3 is traversed, can matching all operands using RegexB, (for "-" as negative processing, "+" is at positive number
Reason)
16 and -14.7 two real numbers are matched from S3, then matched result is directly added, obtains 1.3
The method can be generalized to the case where multiple operands:
Such as expression formula is " -40-6-4+2.1-91 ", can match -40, -6, -4 ,+2.1, -91 five using RegexB
A real number, is put into 5 numbers matched the array of type real, and traversal calculates the result that can be obtained by expression formula
