Thank you Ravinder for your response. Sorry if I question is not clear.

Condition 1 - Unique value of column one which are 3330690 and 0640829
Condition 2 - Unique value of column one 3330690 is associated with 2 distinct value of column 2 which are 373846 and 373847. The unique value of column 1 which is 0640829 is associated with unique value of column 2 which is 459725.

Hence output is expected as below

Code:
2 3330690 
1 459725

Hope this clarifies.
