Time complexity is the relative running time of some code. Heapifying means building a heap. This arti-cle explains heapify time complexity and the C language.
I read somewhere that the C++ STLparital_sortfunction (used to findk smallest numbers) has a running time complexity ofO(n.logk). It achieves this by going through the entire data, maintaining ak-sized max-heap, throwing away the top whenever size exceeds k, and in the end printing the...

When we use a heap to pop or push values, we will perform the function of heapify at the same time to ensure the heap is in the form of a min-heap. Heapify is the process of creating a heap data structure from a binary tree. Similarly, before each element is pushed into the heap...
