The string is called alternating if no two adjacent characters are equal. For example, the strings "010" and "1010" are alternating, while the string "0100" is not.Any two characters may be swapped, even if they are not adjacent.

except in virtualized environments where a virtual machine snapshot or virtual machine introspection (Javaid et al., 2012) can be used to more consistently capture or introspect both RAM and the swap file, it is generally very difficult in a running system to gather both in a consistent fashio...
实时上java会分两步写入这个long变量,先写32位,再写后32位。这样就线程不安全了。如果改成下面的就线程安全了: 1 privatevolatilelongfoo; 因为volatile内部已经做了synchronized. CAS无锁算法 要实现无锁(lock-free)的非阻塞算法有多种实现方法,其中CAS(比较与交换,Compare and swap)是一种有名的无锁算法。CAS...
