string-matching

问题 I want to get all the matching numbers(only numbers example '0012--22') or numbers which contain some text (example 'RF332') corresponding to it which matches with a list of strings provided("my_list" in the code). The format in which the text with number will be present is like separated by a space or two. Providing sample input file for reference. This is the input file: $cat input_file some text before Expedien: 1-21-212-16-26 some random text Reference RE9833 of all sentences. abc 123 456

问题 Is there a working example of the Boyer-Moore string search algorithm in C? I've looked at a few sites, but they seem pretty buggy, including wikipedia. Thanks. 回答1: The best site for substring search algorithms: http://igm.univ-mlv.fr/~lecroq/string/ 回答2: There are a couple of implementations of Boyer-Moore-Horspool (including Sunday's variant) on Bob Stout's Snippets site. Ray Gardner's implementation in BMHSRCH.C is bug-free as far as I know 1 , and definitely the fastest I've ever seen or

问题 My question is: Is there a UTL_MATCH-like function which works with a CLOB rather than a VARCHAR2 ? My specific problem is: I'm on an Oracle database. I have a bunch of pre-written queries which interface with Domo CenterView. The queries have variables in them defined by ${variableName} . I need to rewrite these queries. I didn't write the original so instead of figuring out what a good value for the variables should be I want to run the queries with the application and get what the query

Example: If I have strings like these: abc123xyz456()* ^%$111u222 Then convert it to: 123456 111222 回答1: How about regular expressions?

问题 How do I verify in C# that the password contains at least X uppercase letters and at least Y numbers, and the entire string is longer than Z? Thanks. 回答1: Password Strength: First, I would read up on password strength, and double-check your policy to make sure you were doing the right thing (I couldn't tell you off hand): http://en.wikipedia.org/wiki/Password_strength https://www.grc.com/haystack.htm http://xkcd.com/936/ (a joke, but good food for thought) Then I'd check other questions:

问题 Is there a way to do something similar to SQL's LIKE syntax on a pandas text DataFrame column, such that it returns a list of indices, or a list of booleans that can be used for indexing the dataframe? For example, I would like to be able to match all rows where the column starts with 'prefix_', similar to WHERE <col> LIKE prefix_% in SQL. 回答1: You can use the Series method str.startswith (which takes a regex): In [11]: s = pd.Series(['aa', 'ab', 'ca', np.nan]) In [12]: s.str.startswith('a',

问题 for my research I have to match two data sets containing fund information. Unfortunately there is no common identifier. The good thing is that I have an identifier in both documents for the document number which however can contain multiple funds. If there are multiple funds in the document (e.g. 20) I can only match via the fund's name which can differ sometimes slightly. Note that the number of funds per document is identical in noth data sets. After searching a little bit I tried to use

问题 I have a file with the top 1000 baby names. I want to ask the user for a name...search the file...and tell the user what rank that name is for boy names and what rank for girl names. If it isn't in boy names or girl names, it tells the user it's not among the popular names for that gender. The file is laid out like this: Rank Boy-Names Girl-Names 1 Jacob Emily 2 Michael Emma . . . Desired output for input Michael would be: Michael is 2nd most popular among boy names. If Michael is not in girl
