Tang jianfa said that 2.8 had been greatly enhanced, and 2.8 was a bit grievance. Therefore, the MongoDB Marketing Department named 3.0 .) The version introduces the WiredTiger storage engine MMAP that supports Latch-free and Non-blocking algorithms. Therefore, the wiredtiger parameter must be added before use.

Problem
In his computation Sutra, Zhang qiujian, a Chinese ancient mathematician, proposed the famous question of "buying a hundred chickens for a hundred dollars": Wong Yi, worth five yuan, and mother of a rooster, valuable 3, chicken 3, valuable 1, yuan to buy a hundred chickens, Q Weng, Mother, and chicks ry?
If it is a column equation:
Set rooster X, hen y, and chicken to 100-x-y.
There are 5x + 3y + (100-x-y)/3 = 100
Resolved to 7X + 4y = 100

Implement Pow (x, n).Idea: Although the problem is simple, I didn't do it at first.Where I'm not concise, there are:1. First I thought of the symbolic question, so I used flag to mark the positive and negative of X.
