Memcached Challenge

Inspired by Arthur O’Dwyer's Blog, I start this challenge as an engineering interview (a little big different from the blog):

1. Fork memcached - master, and build it.

I suggest using Linux os to do this, since there may be errors in compile stage in MacOS (not test on Windows).

git clone --depth=1 https://github.com/memcached/memcached.git

sh autogen.sh
./configure
make

2. Implement a mult method to multiply a unsigned instance number to a stored number.

Here is the demo from my impl:

I DO need some suggests, just leave a issue.
