when I look at others' solution which passes the test, I find that for 10.1 and 10.01, they are the same version. This does not make sense.
10.1 can be separated into 2 sections, 10 and 1. The same way, 10.01 can be separated into 2 sections,10 and 01. It is easy to understand that the first section is equal. But why is 01 equal to 1? In fact, this is a common regulation. In version management, you should ignore the 0s ahead.
