WebFeb 11, 2024 · First of all, we think the time complexity of min_heapify, which is a main part of build_min_heap. min_heapify repeats the operation of exchanging the items in an array, which runs in constant time. So the time complexity of min_heapify will be in proportional to the number of repeating. WebJun 15, 2024 · So the worst-case time complexity should be the height of the binary heap, which is log N. And appending a new element to the end of the array can be done with constant time by using cur_size as the index. As a result, the total time complexity of the insert operation should be O (log N).
