WebInsertion: The time complexity for adding an element to a binary heap, where n is the number of entries in the heap, is O(log n). This is because the height of a binary heap is log n, so in the worst-case scenario, it would take O(log n) time to compare and swap the inserted element from the leaf level to the root level of the heap.
