bsort
Fast positive integer sorting algorithm using radix sort written in C++. The algorithm was based on @rcgldr original code as discussed in this thread.
Compilation:
g++ bsort.cc -o bsort.x -Wall -O2
Usage:
./bsort.x [-r record length in bytes] [-k key length in bytes] [-s key initial byte] [-o output filename] filename
The input file should be a binary file. Code can be easily modified to handle ascii files.
