extends Object

1481 - Least Number of Unique Integers after K Removals\. Medium Given an array of integers `arr` and an integer `k`. Find the _least number of unique integers_ after removing **exactly** `k` elements**.** **Example 1:** **Input:** arr = [5,5,4], k = 1 **Output:** 1 **Explanation:** Remove the single 4, only 5 is left. **Example 2:** **Input:** arr = [4,3,1,1,3,3,2], k = 3 **Output:** 2 **Explanation:** Remove 4, 2 and either one of the two 1s or three 3s. 1 and 3 will be left. **Constraints:** * `1 <= arr.length <= 10^5` * `1 <= arr[i] <= 10^9` * `0 <= k <= arr.length`
