For coding question you have 30 minutes to solve it. I did most optimal way in a short while and additional added test function which tests real function. The lottery will draw 8 balls labeled 1 to 20. The balls will be picked out of bag and if the number rules below are valid we accept that number as part of the lottery numbers and return the ball back in the bag. We will do this until we get 8 numbers. Rules are: - The same number can appear more than once - No more than 2 occasions of duplicates are allowed Your function will return the results sorted in ascending order. Example valid draws: [1,2,3,4,5,6,7,8] [1,1,2,2,2,6,7,8] Example not allowed: [1,1,2,2,3,3,7,8] not allowed bcs the re are 3 duplicates here 1,2,3
