That is, if you were to insert the values 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 in that order. When removing the smallest item from a min-heap, you take the last item from the heap and sift it down from the top. WebBuilding a heap We can build the heap from an array of n items using two methods. In the first method, we successively perform the insert operation on the heap. In n insert operations, we can build the heap from the array. Since each insert operation takes O (log n) time and there are n such operations, the complexity of this method is O (nlog n). dr shantir practice e17
