Teaching Kids Programming: Videos on Data Structures and Algorithms 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 = , k = 1 Output: 1 Explanation: Remove the single 4, only 5 is left. Example 2: Input: arr = , 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 <= 10^9 0 <= k <= arr.length Least Number Continue Reading »
