2. Merging

There are two main functions: Splice () and merge ()
Splice () has three forms of invocation:
The first type: List1.splice (it1, list2). Copies all the elements in the List2 to List1. The starting position in List1 is it1. After the copy is finished, List2 will be empty.

The second form of invocation:
List1.splice (it1, List2, it2)
This function is to list2 the elements in the it2, starting at the beginning of the List1, and cutting to the place where the it1 start.
The third form of invocation:
List1.splice (it1, List2, It2begin, It2end)
Use of the merge function:
Form: List1.merge (LIST2)
Note: Before you use merge, you must make List1 and list2 in order. Also, the list1 is still orderly after the merger.
