@Jayanaka-98 can we organize this nicely. for example,
src/ folder, Readme, main.jac, proper file naming (!DSP.jac --> main_dsp.jac)
maybe I am wrong here, better have one implementation, other than multiple (it confuses the peeps), after all this is a git repo know we can revisit commit if need to check previous implementations
