WebASK AN EXPERT. Engineering Computer Science Show that by adding values to a skew heap in the right sequence, any binary tree that possesses the heap property can be created. (This understanding is crucial to comprehending why an amortised accounting approach is required.) Show that by adding values to a skew heap in the right sequence, … The most important variation to the basic algorithm, which is included in all practical implementations, is a heap-construction algorithm by Floyd which runs in O(n) time and uses siftdown rather than siftup, avoiding the need to implement siftup at all. Rather than starting with a trivial heap and repeatedly adding leaves, Floyd's algorithm starts with the leaves, observing that they are trivial but valid heaps by themselves, and then adds parents…
