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).
