{"contest_date":"2023-05-07T00:00:00","contest_id":"weekly-contest-344","difficulty":"easy","platform":"leetcode","question_content":"You are given a 0-indexed array nums of length n.\nThe distinct difference array of nums is an array diff of length n such that diff[i] is equal to the number of distinct elements in the suffix nums[i + 1, ..., n - 1] subtracted from the number of distinct elements in the prefix nums[0, ..., i].\nReturn the distinct difference array of nums.\nNote that nums[i, ..., j] denotes the subarray of nums starting at index i and ending at index j inclusive. Particularly, if i > j then nums[i, ..., j] denotes an empty subarray.\n \nExample 1:\n\nInput: nums = [1,2,3,4,5]\nOutput: [-3,-1,1,3,5]\nExplanation: For index i = 0, there is 1 element in the prefix and 4 distinct elements in the suffix. Thus, diff[0] = 1 - 4 = -3.\nFor index i = 1, there are 2 distinct elements in the prefix and 3 distinct elements in the suffix. Thus, diff[1] = 2 - 3 = -1.\nFor index i = 2, there are 3 distinct elements in the prefix and 2 distinct elements in the suffix. Thus, diff[2] = 3 - 2 = 1.\nFor index i = 3, there are 4 distinct elements in the prefix and 1 distinct element in the suffix. Thus, diff[3] = 4 - 1 = 3.\nFor index i = 4, there are 5 distinct elements in the prefix and no elements in the suffix. Thus, diff[4] = 5 - 0 = 5.\n\nExample 2:\n\nInput: nums = [3,2,3,4,2]\nOutput: [-2,-1,0,2,3]\nExplanation: For index i = 0, there is 1 element in the prefix and 3 distinct elements in the suffix. Thus, diff[0] = 1 - 3 = -2.\nFor index i = 1, there are 2 distinct elements in the prefix and 3 distinct elements in the suffix. Thus, diff[1] = 2 - 3 = -1.\nFor index i = 2, there are 2 distinct elements in the prefix and 2 distinct elements in the suffix. Thus, diff[2] = 2 - 2 = 0.\nFor index i = 3, there are 3 distinct elements in the prefix and 1 distinct element in the suffix. Thus, diff[3] = 3 - 1 = 2.\nFor index i = 4, there are 3 distinct elements in the prefix and no elements in the suffix. Thus, diff[4] = 3 - 0 = 3.\n\n \nConstraints:\n\n1 <= n == nums.length <= 50\n1 <= nums[i] <= 50","question_title":"find-the-distinct-difference-array","starter_code":"class Solution:\n    def distinctDifferenceArray(self, nums: List[int]) -> List[int]:\n        "}
