Today, I found the java interview programming questions in the Forum and thought about it. I found that I forgot my original programming basics.

Question: How many equals 2x8 in the most efficient way?

Along with the targeted thinking, I thought of 2x8. Later I thought that this efficiency was definitely not the best. think of the concept of a computer system, where a multiplier is composed of a multiplier and should be quickly added. after reading the answer, I suddenly realized that it was originally implemented through the displacement operation.

Answer: 2 <3

Are you correct?
