BINARY TREES AND HEAPS IN JAVA
... We can do this in O(log n) time, using a binary heap, by following this algorithm: (1) Add the element on the bottom level of the heap. (2) Compare the added element with its parent; if they are in the correct order, stop. (3) If not, swap the element with its parent and return to the previous step. ...
