Hi,laozhao
are you gonna sort all the keys?Maybe you can sort all the keys by
implentmenting partition function, something like range-partition.for example,
there are 100 digits. you can design 5 partitions
[1-20],[20,40],[40,60],[60,80],[80,100], deviding the different digits into
different partitions.
