Problem about intervals and difference array with 2 follow-ups
Given an array nums, return diff where diff[i] = (number of distinct elements in nums[0..i]) minus (number of distinct elements in nums[i+1..n-1]). This is solved by tracking distinct counts for prefixes and suffixes (e.g., with sets) to compute all differences efficiently.
