This implemenation sorts integer arrays with bucket sort in C. Tested for up to 2.000.000 elements and it comes with its own test suit implementation.
sudo apt-get install gcc python-pip
sudo pip install when-changed
comile and run:
make default app=bucketsort_test
auto re-compile and re-run on file change:
make watch app=bucketsort_test
app= has its default value set to bucketsort_test, therefore you could easily skip this parameter.
