  • mathing string in python

    - by nani
    Write two functions, called countSubStringMatch and countSubStringMatchRecursive that take two arguments, a key string and a target string. These functions iteratively and recursively count the number of instances of the key in the target string. You should complete definitions forthe remaining problems, we are going to explore other substring matching ideas. These problems can be solved with either an iterative function or a recursive one. You are welcome to use either approach, though you may find iterative approaches more intuitive in these cases of matching linear structures

  • How can I check if a Perl array contains a particular value?

    - by Mel
    I am trying to figure out a way of checking for the existence of a value in an array without iterating through the array. I am reading a file for a parameter. I have a long list of parameters I do not want to deal with. I placed these unwanted parameters in an array @badparams. I want to read a new parameter and if it does not exist in @badparams, process it. If it does exist in @badparams, go to the next read.

  • How do I get characters common to two vectors in C++?

    - by Sam Phelps
    I am trying to compare two vector objects, and return a single vector containing all the chars which appear in both vectors. How would I go about this without writing some horribly complex manual method which compares every char in the first vector to every char in the second vector and using an if to add it to a third vector (which would be returned) if they match. Maybe my lack of real experience with vectors is making me imagine this will be harder than it really is, but I suspect there is some simplier way which I have been unable to find through searching.

  • Split string into sentences based on periods

    - by rookie
    Hi all, I have written this piece of code that splits a string and stores it in a string array:- String[] sSentence = sResult.split("[a-z]\.\s+"); However, I've added the [a-z] because I wanted to deal with some of the abbreviation problem. But then my result shows up as so:- Furthermore when Everett tried to instruct them in basic mathematics they proved unresponsiv I see that I loose the pattern specified in the split function. Its okay for me to loose the period, but loosing the last letter of the word disturbs its meaning. Could some one help me with this and in addition also could someone help me with dealing with abbreviations? Like because I split the string based on periods, I do not want to loose the abbreviations. Thanks in advance

  • .Net Round-trip Types

    - by Fujiy
    I making a method that generate a unique string key for some parameters. But the same key if call with same values. I just accept primitive types, string, DateTime, Guid, and Nullable(since I append types together, I can distinguish who is int and who is int?), because I can convert all to string without lost values or precision.(for float and double a use ToString("R"), to DateTime ToString("O")). Exists a easy way to know which types I can transform in strings without conflict? And how do this transform(how I said before, float, double and datetime have specific ways) Thanks

  • Comparing objects and inheritance

    - by ereOn
    Hi, In my program I have the following class hierarchy: class Base // Base is an abstract class { }; class A : public Base { }; class B : public Base { }; I would like to do the following: foo(const Base& one, const Base& two) { if (one == two) { // Do something } else { // Do something else } } I have issues regarding the operator==() here. Of course comparing an instance A and an instance of B makes no sense but comparing two instances of Base should be possible. (You can't compare a Dog and a Cat however you can compare two Animals) I would like the following results: A == B = false A == A = true or false, depending on the effective value of the two instances B == B = true or false, depending on the effective value of the two instances My question is: is this a good design/idea ? Is this even possible ? What functions should I write/overload ? My apologies if the question is obviously stupid or easy, I have some serious fever right now and my thinking abilities are somewhat limited :/ Thank you.

  • Compute hex color code for an arbitrary string

    - by user222164
    Heading Is there a way to map an arbitrary string to a HEX COLOR code. I tried to compute the HEX number for string using string hashcode. Now I need to convert this hex number to six digits which are in HEX color code range. Any suggestions ? String [] programs = {"XYZ", "TEST1", "TEST2", "TEST3", "SDFSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS"}; for(int i = 0; i < programs.length; i++) { System.out.println( programs[i] + " -- " + Integer.toHexString(programs[i].hashCode())); }

  • Simple, Custom Parsing with c++

    - by bradkovach
    Hi! I have been reading SO for some time now, but I truly cannot find any help for my problem. I have a c++ assignment to create an IAS simulator. Here is some sample code... 0 1 a 1 2 b 2 c 3 1 10 begin 11 . load a, subtract b and offset by -1 for jump+ 11 load M(0) 12 sub M(1) 13 sub M(3) 14 halt Using c++, I need to be able to read these lines and store them in a "memory register" class that I already have constructed... For example, the first line would need to store "1 a" in register zero. How can I parse out the number at the line beginning and then store the rest as a string? I have setup storage using a class that is called using mem.set(int, string);. int is the memory location at the beginning of the line and string is the stored instruction.

  • Writing String into a File

    - by Halo
    I'm implementing a WebScript using Alfresco's JavaScript. l'm trying to insert string to a file, but I can't do it. When I write another file's content like: file.properties.content.write(content); It works, and the file's contents are copied into my file. But I can't insert string directly, like: file.properties.content.write("Stuff like that"); it gives an exception. How can I write string into this file?

  • C#, Fastest (Best?) Method of Identifying Duplicate Files in an Array of Directories

    - by Nate Greenwood
    I want to recurse several directories and find duplicate files between the n number of directories. My knee-jerk idea at this is to have a global hashtable or some other data structure to hold each file I find; then check each subsequent file to determine if it's in the "master" list of files. Obviously, I don't think this would be very efficient and the "there's got to be a better way!" keeps ringing in my brain. Any advice on a better way to handle this situation would be appreciated.

  • WSDL vs DLL. Which is better?

    - by Lopper
    I would like to create a reusable interface to transfer some proprietary information over the TCP/IP connection. If given only the choice of either WSDL or DLL, what are the pros and cons of using each? This is assuming that Windows OS is used.

  • Best way to initialise / clear a string variable cocoa

    - by Spider-Paddy
    I have a routine that parses text via a loop. At the end of each record I need to clear my string variables but I read that someString = @"" actually just points to a new string & causes a memory leak. What is the best way to handle this? Should I rather use mutable string vars and use setString:@"" between iterations?

  • Writing Strings to files in python

    I'm getting the following error when trying to write a string to a file in pythion: Traceback (most recent call last): File "export_off.py", line 264, in execute save_off(self.properties.path, context) File "export_off.py", line 244, in save_off primary.write(file) File "export_off.py", line 181, in write variable.write(file) File "export_off.py", line 118, in write file.write(self.value) TypeError: must be bytes or buffer, not str I basically have a string class, which contains a string: class _off_str(object): __slots__ = 'value' def __init__(self, val=""): self.value=val def get_size(self): return SZ_SHORT def write(self,file): file.write(self.value) def __str__(self): return str(self.value) Furthermore, I'm calling that class like this: def write(self, file): for variable in self.variables: variable.write(file) I have no idea what is going on. I've seen other python programs writing strings to files, so why can't this one? Thank you very much for your help.

  • VB.Net HTTPWebRequest Speed is slow comparing Python URLOpen

    - by regexhacks
    Hi I am coding a web-crawler which will crawl the websites and selectively parse different sections of a web site. I am a .Net developer so the choice was obvious that I did it in .Net but the speed was very slow which included downloading and parsing of HTMLPages Then I tried to just download the contents first using .Net and then same domains using python but the python was very impressive in downloading data. I have achieved downloading using python but the later part is not that easy to code in python, which obviously i don't want to do. The same batch of domain which took 100 seconds in Python was taking 20 minutes in .Net based crawler I tried http://www.eqlit.com/ to download and in took 8 seconds in Python and same was taking 100 Seconds in .Net crawler Does anyone anyone have any idea why this is slow in .Net but fast in python?

  • Is Linq Faster, Slower or the same?

    - by Vaccano
    Is this: Box boxToFind = AllBoxes.Where(box => box.BoxNumber == boxToMatchTo.BagNumber); Faster or slower than this: Box boxToFind ; foreach (Box box in AllBoxes) { if (box.BoxNumber == boxToMatchTo.BoxNumber) { boxToFind = box; } } Both give me the result I am looking for (boxToFind). This is going to run on a mobile device that I need to be performance conscientious of.

  • how to read string part in java

    Hello everyone, I have this string : <meis xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" uri="localhost/naro-nei" onded="flpSW531213" identi="lemenia" id="75" lastStop="bendi" xsi:noNamespaceSchemaLocation="http://localhost/xsd/postat.xsd xsd/postat.xsd"> How can I get lastStop property value in JAVA? This regex worked when tested on http://www.myregexp.com/ But when I try it in java I don't see the matched text, here is how I tried : import java.util.regex.Pattern; import java.util.regex.Matcher; public class SimpleRegexTest { public static void main(String[] args) { String sampleText = <meis xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" uri=\"localhost/naro-nei\" onded=\"flpSW531213\" identi=\"lemenia\" id=\"75\" lastStop=\"bendi\" xsi:noNamespaceSchemaLocation=\"http://localhost/xsd/postat.xsd xsd/postat.xsd\">"; String sampleRegex = "(?<=lastStop=[\"']?)[^\"']*"; Pattern p = Pattern.compile(sampleRegex); Matcher m = p.matcher(sampleText); if (m.find()) { String matchedText = m.group(); System.out.println("matched [" + matchedText + "]"); } else { System.out.println("didn’t match"); } } }

  • How do I deal with connection strings in a Click-Once application?

    - by Pwninstein
    I'm thinking of building a Click-Once application, and am trying to wrap my head around how to handle the whole connection string issue. The problem is the following: I want to use EF to get data directly from each client, thus requiring each client to have a connection string configured (this is not the issue). How do I deal with clients that are not on the same domain as the SQL Server being queried? In other words, if I tried to run my app from home as opposed to from work, what should my connection string look like? Would I need to configure my SQL Server differently to allow this scenario? Thanks in advance!

  • Visual Studio 2010 compile error with std::string?

    - by AJG85
    So this is possibly the strangest thing I've seen recently and was curious how this could happen. The compiler gave me an error saying that std::string is undefined when used as a return type but not when used as a parameter in methods of a class! #pragma once #include <string> #include <vector> // forward declarations class CLocalReference; class CResultSetHandle; class MyClass { public: MyClass() {} ~MyClass {} void Retrieve(const CLocalReference& id, CResultSetHandle& rsh, std::string& item); // this is fine const std::string Retrieve(const CLocalReference& id, CResultSetHandle& rsh); // this fails with std::string is undefined?!?! }; Doing a Rebuild All it still happened I had to choose clean solution and then Rebuild All again after for the universe to realign. While it's resolved for the moment I'd still like to know what could have caused this because I'm at a loss as to why when there should be no conflicts especially when I always use fully qualified names for STL.

  • Compare string with all values in array

    I am trying to fumble through python, and learn the best way to do things. I have a string where I am doing a compare with another string to see if there is a match: if paid[j].find(d)>=0: #BLAH BLAH If 'd' were an array, what is the most efficient way to see if the string contained in paid[j] has a match to any value in 'd'?
