. In fact, its time complexity is like this. It's strange. But it does. It can be seen that this algorithm is not an efficient algorithm. When n reaches a certain value, the output speed will last for a long time. For example, if n is 100, a 2 GHz processor can process 2G in 1 s, that is, 2 ^ 31, and 1 year is equivalent to 2 ^ 25 power, so when n is 100, it takes 2 ^ (100-25-31) years. How long does it take to wait ..........
So this is not a reasonable algorithm ......

2. Rent an enterprise mailbox
The Enterprise mailbox is used to rent the email server space created by the carrier. The advantage of renting an enterprise mailbox is that the enterprise does not require hardware costs or maintenance by technicians. Disadvantages of renting an enterprise mailbox: data is on the carrier's server, and data security is not guaranteed. enterprise mail features are popular and can only be used for sending and receiving simple emails.
