For many algorithms, the best program is usually sent out, and the optimization is the most thorough (so far), that is, the time is the fastest and the space is the least.
They are generally based on the original idea and the final result obtained after many optimizations and improvements.
Optimization is very important to the program, it represents the progress of science and technology.
Therefore, the best program is the most important.
The study and exploration of good algorithms.
It is our responsibility.
