Web1207. Unique Number of Occurrences. Given an array of integers arr, return true if the number of occurrences of each value in the array is unique or false otherwise. Input: arr = [1,2,2,1,1,3] Output: true Explanation: The value 1 has 3 occurrences, 2 has 2 and 3 has 1. No two values have the same number of occurrences. WebFeb 22, 2024 · Space is O (n * m * cost). Space can be further optimized to O (m * cost) as only [i-1] matters. Can also be further optimized to use only one prefix dp array. dp [i] [j] [k] represents the number of arrays of size i whose max value is j and total cost is k. cum [i] [j] [k] = dp [i] [1] [k] + dp [i] [2] [k] + ... + dp [i] [j] [k].
