Hi,
I Have similar requirement. If anyone solve this, pls let me know. Explanation of the problem.
Consider i have two columns with combinations of numbers. I want to pick the genuine combinations of numbers which doesnt involve in other valid conbinations. For ex.,
Num1 Num2
6 2
2 1
2 3
4 6
3 1
8 9
3 9
6 8
My result should be
6 2
3 1
8 9
Can this be done without using loops...
