Distinct Value of each column !

Hi,
I've table with following structre
create table #test
(a int,
b varchar(10),
c varchar(10)
)
insert into #Test values ('1','a','x')
insert into #Test values ('2','b','y')
insert into #Test values ('3','c','y')
insert into #Test values ('3','b','1')
insert into #Test values ('4','a',null)
insert into #Test values ('1',null,null)
now i want distinct value of
each column like
A B C
--
1 a x
2 b y
3 c 1
4 null null
How do i get this type of resultset ?
