The output list should also be sorted from lowest to highest. Your algorithm should run in linear time on the length of the output list. 2 数据结构有序链表问题。 Write a function to merge two sorted linked lists. The input lists have their elements in sorted order, from lowest to highest...
Use the ORDER and UNIQUE hints in theOPENROWSET(BULK...)clause, to specify how the source data file is sorted. By default, the bulk operation assumes the data file is unordered. Therefore, it's important that the source data is sorted according to the clustered index on the target table ...
