B: Hexagram
A Hexagram is a pointed star, sometimes called the Star of David. Given these
numbers:
There are four unique ways of assigning the numbers to vertices of the hexagram
such that all of the sets of four numbers along the lines have the same sum
in this case All other ways may be obtained from these by rotation andor
reflection.
Given is aisunct numvers, in now many ways, uisregarung rotauons anu
reflections, can you assign the numbers to the vertices such that the sum of the
numbers along each of straight lines passing through vertices is the same?
The Input
There will be several test cases in the input. Each test case will consist of twelve
unique positive integers on a single line, with single spaces separating them. All
of the numbers will be less than The input will end with a line with
twelve s
The Output
For each test case, output the number of ways the numbers can be assigned to
vertices such that the sum along each line of the hexagram is the same. Put
each answer on its own line. Output no extra spaces, and do not separate
answers with blank lines.
