, then cannot play. Here is a reference to the applicable scope of the cardinality sort described in an article.
The cardinality is sorted from low to high, so that after the last count is sorted, the array is ordered. The principle is that for the data to be sorted, the overall weight is unknown, first by the weight of a small factor, and then weighted by a significant factor. For example, compare time, sort by day, sort by month, sort by year, order only three times. But it's not so e

But more importantly, only types are used to solve such problems, neither polymorphic functions (polymorphic function) nor language primitives (language primitive) or other types of help, only types!
This is the detail that stuck to me.
Programmers who move from C + + and Java to go are nostalgic for the way they use type programming, especially concepts such as inheritance and subclasses. Maybe I'm just a layman about "type", but I really don't see any goo

knowing that there is a class such as test, because the sequencer has thousands, Each person's name is different, want to do things are different, so thread only know one! That's runnable. Thread knows runnable and knows there is a run method inside runnable. Once the thread's Start method is called, the run in the Runnable method is automatically run by the thread. So, when we inherit our class (which should be called implementation interface) since
