进程 vs 线程
http://www.ruanyifeng.com/blog/2013/04/processes_and_threads.html
操作系统的设计，因此可以归结为三点：
（1）以多进程形式，允许多个任务同时运行；
（2）以多线程形式，允许单个任务分成不同的部分运行；
（3）提供协调机制，一方面防止进程之间和线程之间产生冲突，另一方面允许进程之间和线程之间共享资源。
1427. Split Array into Fibonacci Sequence
Description 中文 English Given a string S of digits, such as S = "123456579", we can split it into a Fibonacci-like sequence [123, 456, 579]. Formally, a Fibonacci-like sequence is a list F of non-negative integers such that: 0 <= F[i] <= 2^31 - 1, (that is, each integer fits a 32-bit signed integer type); F.length >= 3; and F[i] + F[i+1] = F[i+2] for all 0 <= i < F.length - 2. Also, note that when splitting the string into pieces, each piece must not have extra leading zeroes, except if the piece is the number 0 itself. Return any Fibonacci-like sequence split from S, or return [] if it cannot be done. 1 <= S.length <= 200 S contains only digits. Have you met this question in a real interview? Yes Problem Correction Example Example 1: Input: "123456579" Output: [123,456,579] Example 2: Input: "11235813" Output: [1,1,2,3,5,8,13] Example 3: Input: "112358130" Output: [] Ex...
