The answer
The time complexity is O(N log K), as you process N elements, and each insertion/deletion into a heap of size K takes log K time.
Generalizing to Find the k-th Largest Element
What is the time complexity of the Heap approach?
More FAQs in Generalizing to Find the k-th Largest Element
It is a generalized problem where you must find the element that would sit at the K-th position if the array were sorted in descending order.
Because managing K discrete variables manually requires massive amounts of hardcoded logic, making it impossible to write dynamically for an unknown K.
A Min-Heap is a specialized tree-based data structure where the parent node is always smaller than its children, meaning the absolute smallest value is always at the top.
