Given a list of integers, calculate the sum of the first 3 unique numbers. If there are less than 3 unique numbers in the list, calculate the sum of all unique numbers in the list.
List: [1,4,5,7,2,1,4,2,7,9]
In this case, the sum would be 12 (1 + 4 + 7) since there are only 3 unique numbers in the list. | codefeedback | [
