Distinct values in sub Group

[deega]

Hi All, 

The solutions of the community have always helped me and saved lot of time too. Here I am again with another problem. It is looking very simple but I am not able to do it by simple program.

My input is as follows

1	A
1	A
1	B
2	A
2	A
2	A
2	B
2	B
3	A
3	B
3	C
3	C
3	C
3	C
4	D
4	D
4	E
5	A
5	B
5	C

and I am looking for output where I get unique values of sub-group as follows

1	A
1	B
2	A
2	B
3	A
3	B
3	C
4	D
4	E
5	A
5	B
5	C

Thanks in advance !
