C99 Macro to build a quoted string literal after evaluation

I'm developing an embedded application in C99, and the project contains some integer constants defined like: #define LEVEL1 0x0000 #define LEVEL2 (LEVEL1 + 1) It has since become useful to keep track of these values for logging purposes, so I would like to use a macro to create a string literal from the evaluated versions of t...

Suffix Array Implementation in Java

I'm looking to write an efficient n-order Markov chain method to generate random text strings given a set of example text.

Reference-counting of std::string

I'm looking at the code for basic_string (that is bundled with g++ 4.2.1).

Hi everyone, I have an ordered list (a dictionary - 100K words) and many words to seach on this list frequently. So performance is an issue. I know that a HashSet.contains(theWord) or Collections.binarySearch(sortedList, theWord) are very fast. But I am actually not looking for the whole word. What I want is let's say searching for "s...
