How to find missing numbers in a seperate column from 2 columns

Hello,

I have data in 2 columns (given below) and want to compare both the columns and want to get the missing numbers in seperate column. e.g
Column 1 Column 2
1 6
3 7
5 7
7 3

I want to compare both the colunms and want to get the numbers in column 3, which are not in column 1 but are in column 2. And numbers in column 4, which numbers are not in column 2 but are in clumn 1.

I hope question is clear.

Regards,
Sudhir
