There is a table in database. This table contains unduplicated natural numbers. There may be gaps in the sequence of natural numbers in the table. You need to output missing numbers.
Table of natural numbers: declare @values as table ([number] int not null).
Test data: insert into @values([number]) values (1), (2), (3), (5), (9).
Result: declare @missing as table ([left] int not null, [right] int not null).

/*
Twin Strings
Two strings, a and b, are said to be twins only if they can be made equivalent by performing some number of operations on one or both strings. There are two possible operations:

SwapEven: Swap a character at an even-numbered index with a character at another even-numbered index.
SwapOdd: Swap a character at an odd-numbered index with a character at another odd-numbered index.
 
For example, a = "abcd" and b = "cdab" are twins because we can make them equivalent by performing operations. Alternatively, a = "abcd" and b = "bcda" are not twins (operations do not move characters between odd and even indices), and neither are a = "abc" and b = "ab" (no amount of operations will insert a 'c' into string b).

Complete the twins function in the provided code. It has two parameters:
