What is the smartest way of searching through an array of strings for a matching string in Perl?
One caveat, I would like the search to be case-insensitive
so "aAa" would be in ("aaa","bbb")
I just finished coding a complex job assignment application where a lot of the work was done using priority queues. When I deployed, however, I discovered the web server ran PHP 5.2.
Has there been an implementation for PHP<5.3 that can server as a drop-in replacement for SPLPriorityQueue?
I'm developing a cms for a company that has multiple regional sites (us, uk, china, russia, etc..). Should I use a separate database for each of these sites or use a single database with a 'site' field in each table? My main concern is the table language encoding (ie, can storing strings in different langauges in the same table cause problems, such as sorting issues).
I have the following dilemma: I have a list of strings, and I want to find the set of string which start with a certain prefix. The list is sorted, so the naive solution is this:
Perform binary search on the prefixes of the set, and when you find an element that starts with the prefix, traverse up linearly until you hit the top of the subset.
This runs in linear time, however, and I was wondering if anyone can suggest a more efficient way to do it.
Hi
Both do the same thing. What is the most efficient way to compare two strings?
Equals() or Compare()? Are there any differences?
if (String.Equals(StringA, StringB, StringComparison.OrdinalIgnoreCase))
{
// Your code goes here
}
if (String.Compare(StringA, StringB, true) == 0)
{
// Your code goes here
}
I have a file that looks like:
1 1 C C 1.9873 2.347 3.88776
1 2 C Si 4.887 9.009 1.21
I would like to read in the contents of the file, line-by-line. When I only had numbers on the lines I used:
for line in readlines(file):
data = map(float, line.split)
But this only works when all the elements of line.split are numbers. How can I make it store the letters as strings and the numbers as floats?

Is there a standard C library function to escape C-strings?
For example, if I had the C string:
char example[] = "first line\nsecond line: \"inner quotes\"";
And I wanted to print
"first line\nsecond line: \"inner quotes\""
Is there a library function that will do that transformation for me? Rolling my own just seems a little silly.
Bonus points if I can give it a length to escape (so it stops before or beyond the \0).
Hi, I just encounter a strange problem:
var a:ClassA = new ClassA;
var b:ClassA = a;
The program keeps running sometime, the a = null, b = null.
The program is a complex one, I am sure that no part will touch a, and b. My question is, will the runtime(garbage collector) to collect the memory of "a" and then assign a and b to null?
I am confused, thanks!
It looks easy, but I found the implementation tricky. I need that for a simple genetic programming problem I'm trying to implement. The function should, given a node, return the node itself or any of its children such that the probability of choosing a node is normally distributed relative to its depth (so the function should return mostly middle nodes, but sometimes the root itself or the lowest ones - but that's not really necessary if that makes it significantly more complex, if all any node is chosen with equal probability, that's good enough).
Thanks
I have a dictionary:
D = { "foo" : "bar", "baz" : "bip" }
and I want to create new dictionary that has a copy of one of it's elements k. So if k = "baz":
R = { "baz" : "bip" }
what I'v got now is:
R = { k : D[k] }
But in my case k is a complex expression and I've got a whole stack of these. Caching k in a temporary looks about as ugly as the original option.
What I'm looking for is a better (cleaner) way to do this.
I've been working far too long with php and getting bored with it. I also want to learn a new language. I've been using Ruby and like it. I've to decide between Rails and Sinatra, which one would you recommend? Is it true that Sinatra can't be used to build complex apps, and its only for simple apps?
I'm using a list of siteMapProviders in my web.config file.
To retrieve these values in code, I need to specify the names in strings.
Understandably, these is always a mismatch at runtime.
Is there a way to return a strongly typed enum vlaues of these?
I have a function in win32 dll with signature as:
void func1(int a, char*** outData)
int a -- input parameter
char*** outData -- output parameter - pointer to array of char strings
Any idea how to access this in C# using dll import & what should be the signature.
I recently tried a lot of different stuff with lightweight migration. These all work:
1) Rename attributes (with renaming identifier specified)
2) Add attributes
3) Add new entity + new attribute + inverse relationship to an already existing entity
4) remove existing entity + relationships to that entity
= It almost looks like just about anything can be handled with LM. Did I miss something? In which cases am I getting into trouble and need an some more complex approach?
I've been trying to take apart this app which creates a search tree based on keywords, but I'm afraid its a bit too complex for me. Would anyone mind explaining it?
The format is off, so here's a pastebin (is pastie.org down?) version of it.
Any help is appreciated.
Is there a simple way to load test an asp.net application? I've been reading on some microsoft pattern and practices documents that tell you to use ACT which seems kind of hard to use for complex requests.
How does Trie and B+ tree compare for indexing lexicographically sorted strings [on the order some billions]?
It should support range queries as well.
From perf. as well as implementation complexity point of view.
I've got 'no resource found that matches the given name' but everything is set up correctly.
error: Error: No resource found that matches the given name (at 'text' with value '@string/labReminderClear').
In AndroidManifest.xml:
<application android:label="MyName"
.....
In Strings.xml:
<string name="app_name">MyName</string>
...
<string name="labReminderClear">Clear</string>
What could be wrong?
I have a List of executables which may call a certain function. I need to find out which all execs call that function. I know I can do "strings -a " but is there some other better way to find that out. Full code is written in C.
The escape_javascript method in ActionView escapes the apostrophe ' as backslash apostrophe \', which gives errors when parsing as JSON.
Is there a patch to fix this, or an alternate way to escape strings when printing to JSON?
Is it possible to get Autocomplete or Something when i work with the eclipse form editor?
I write a color in the strings.xml and then i want to select it by the propertys for the text color, but there is no autocomplete or something equal
I need to show a webpage (a complex page with script and stuff, no static html) in a frame or something. It's for a desktop application, I'm using python 2.6 + wxPython 2.8.10.1. I need to catch some events too (mostly about changing page). I've found some samples using the webview module in a gtk application, but I couldn't have it works on wx.
I have a C++ string. I need to pass this string to a function accepting char* parameter,
for example - strchr().
a) How do I get that pointer?
b) Is there some funtion equivalent to strschr() that works for C++ strings?
My goal is pretty simple actually but since there are multiple (and seemingly complex ways to do this) I wonder what I need to do... So I have certain runtime libraries (ADF libraries in particular) that are needed to be added to every project. This parent pom file will just have JAR dependencies in it. How can I use this pom file from a child pom file?
