1. Implement a stack that requires an O (1) time complexity to implement push,pop,min (operations that return the minimum value)Algorithm idea: A secondary stack needs to be designed to store the minimum value of elements in the current stack.

9.7 Structure TypeThe 8th chapter mentions that structs and classes are very similar, but structs are value types , and classes are reference types . What does that mean? The most concise way is to use an example to illustrate. The code is as

After changing the topic, there is no odd test ...In fact, it is very easy to find that the near side will only delete the two ends, and the request of the far side will delete the middle.Then, it is obvious that the remaining two points will be
