Web8 de nov. de 2015 · Search in a heap, as it is, will need O (N) time. But if you can take the hit of one time pre-processing of popping out all the elements sequentially in an array, you'll get a sorted array in O (N.logN). Effectively a heap sort. Now your new sorted array can be searched through in O (logN) time. Share Improve this answer Follow WebOtherwise, we shift it up in the tree as long as it violates the heap property. The algorithm for inserting is given below. 1. Insert the new item at the end of the heap. 2. Compare the newly inserted item with its parent. If the parent is larger, stop. If the parent is smaller, swap the item with its parent. 3.
