Performance with Perl Strings
I've been running across a lot of Perl code that breaks long strings up this way: my $string = "Hi, I am a very long and chatty string that just won't"; $string .= " quit. I'm going to keep going, and going, and going,"; $string .= " kind of like the Energizer bunny. What are you going to"; $string .= " do about it?"; From my backgr...
Writing strings into excel using Matlab?
I am writing a cell array of string into Excel from Matlab. I have a cell array data{} that I am trying to write into Matlab. It should writting three large lengths of strings to excel since the strcmp passes 3 times. Currently it is only writing the last set of strings into excel. data = { {1x25} {1x35} {1x20} } looks like this. Also I ...
Is there a .NET function to remove the first (and only the first) occurrence at the start of a string?
I was using the TrimStart function to do the following: var example = "Savings:Save 20% on this stuff"; example = example.TrimStart("Savings:".ToCharArray()); I was expecting this to result in example having a value of "Save 20% on this stuff". However, what I got was "e 20% on this stuff". After reading the documentation on TrimSta...

Phantom folders from Hell (old Vista install) causing Java String.equals() problems...
I'm writing a program that searches directories of a computer. On my own computer I have a drive installed which previously booted Windows Vista. (However, there are drives that do not appear even when "show hidden folders". I can see the folders running cmd, but that doesn't solve my problem.) I don't care so much about the folders...
timeval to string (converting between the two)
I'm trying to pull the two components out of a timeval struct and place them into strings. I'm not having much luck with this. I've attempted casting and converting first to a long and then to a string. I need the most efficient way to do this. Any ideas? I do NOT want to convert to another data structure first (localtime, etc). I need...
Are C# Strings (and other .NET API's) limited to 2GB in size?
Today I noticed that C#'s String class returns the length of a string as an Int. Since an Int is always 32-bits, no matter what the architecture, does this mean that a string can only be 2GB or less in length? A 2GB string would be very unusual, and present many problems along with it. However, most .NET api's seem to use 'int' to con...
Algorithm to calculate percent difference betweem two blobs of text.
I've been researching on finding an efficient solution to this. I've looked into diffing engines (google's diff-match-patch, python's diff) and some some longest common chain algorithms. I was hoping on getting you guys suggestions on how to solve this issue. Any algorithm or library in particular you would like to recommend? Thanks. ...

How can I put PHP and HTML into a PHP array?
Hi, how can I make this not return an error of: Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING . $day[$i++] = "<tr><?php if(isset($schedule['00:00'])) { ?><td style=\"width:32px\"><?php echo $schedule['00:00'] ?></td><?php } if(isset($schedule['02:00'])) { ?><td style...
case insensitive "subtract" one text from another (php)
(Sorry! Revision regarding the $ character. Explaining via example as well) I need to run a test on two string variables: $a, $b If $a is contained in $b, I need to see if their "difference" ($b-$a) contains the $ character in it. If it does, then return the "difference", else in all other cases, the test should return FALSE Also $a ...
Reverse a string in Java, in O(1)?
Is there any facility in the standard Java libraries that, given a CharSequence, produces the reverse in O(1) time? I guess this is "easy" to implement, just wondering whether it already exists. (I suspect the reason this is not offered is because the "easy" way would actually break multi-char code-points - but in many cases we know we...
Python: problem processing a string

How do I write a function, is_name_attribute(), that checks if a value is a name attribute? That is is_name_attribute('fred') should return True, whereas is_name_attribute('gau...
What code could be used as a string aggregator for Sybase? (Like Oracle's stragg)
In my travels in Oracle, the 'stragg' function, or 'String Aggregator' was life-saving when I had to create dynamic SQL queries on the fly. You can read up about it here: http://www.oratechinfo.co.uk/delimited_lists_to_collections.html The basic use of it was: select stragg(fruit) from food; fruit ----------- apple,pear,banana,strawb...
which of the two practices is more efficient in Java?
I have an object array, I know that the elements are type String, say I need to access them many times. Practice 1: access the element by array index and cast it to String every time I need it. Practice 2: create local String instances and access each of the elements once. Which will run faster? If it's on a mobile device where memor...
Would there be any advantage in comparing pattern and text characters right-to-left instead of left-to-right?
Hi all, This is the exercise in "Introduction to The Design and Analysis of Algorithms". It's a string matching issue. Say I have string ABCD, and have a pattern XY. And want to see if the string contains the pattern. We just assume to use brute-force here, so the left-to-right comparison is comparing A with X, next is comparing B with...
