This is the story of the vessel. The bare data barrel where the numbers are packed and treated into analysis. So when we start data analysis, we keep a vessel for test run, then pack it for loop to run serially.
That $VAR screams, when the moment of doom arrives, an echo from compiler occurs, like a last breath call, Streaming pipes of data, to build a mound, underneath remain windowed ones, which couldn’t make it through, Like a wave, and form an ocean then, rise and sink, till it comes clean, I have that one logic to run, till then I command then to be the wave, Sink back into the ocean bring me the fashion.
P.S. Its painful to watch people trolled by spreadsheets. Start coding.
