copy and paste is also a knowledge my friend. I am sharing this knowledge so that others who did not happen to have the idea will know. I am only spreading the knowledge that has been written by the scholars. Even the lecture you attend, the maths you solve, the science experiment you do is kinda copy and paste!!! It's like F=Ma has been proven yet why are we still copying and pasting this logic into our everyday life???
Now define copy and paste?
