We have already learned about half of it, and the lower part is more interesting. We will learn logical judgment. Before learning in the lower half, we should first perform a test. This test will be a bit difficult and we need to modify others' code. As a programmer, it is inevitable to modify other people's code, and these people often think that their code is perfect. These people are stupid and do not care about others' feelings. Good programmers a
