Solution: Least Number of Unique Integers after K Removals
Understand how to minimize the count of unique integers after removing exactly k elements from an array by using a frequency map and min heap. This lesson guides you through removing the least frequent integers first to achieve the optimal result, with a clear explanation of the algorithm and its time and space complexity.
