Answer:
Explanation:
We start from the bottom-most and rightmost internal node of min Heap and then heapify all internal modes in the bottom-up way to build the Max heap.
To build a heap, the following algorithm is implemented for any input array.
BUILD-HEAP(A) 
    heapsize := size(A)
    for i := floor(heapsize/2) downto 1 
        do HEAPIFY(A, i)
    end for 
Convert the given array of elements into an almost complete binary tree.
Ensure that the tree is a max heap.
Check that every non-leaf node contains a greater or equal value element than its child nodes.
If there exists any node that does not satisfy the ordering property of max heap, swap the elements.
Start checking from a non-leaf node with the highest index (bottom to top and right to left).

Answer: Unified communication
Explanation: Unified communication is the communication technique in which merges various communication routines into a individual business.It works as the phone system which helps in increment of productivity in an organizational business.
The unifying of voice,data/information,video etc is done for optimizing and improving the business that also results in  faster communication rates, secure communication etc.
 
        
             
        
        
        
Health care robots the key word, being "robots" aren't able to act as we can as humans.
Robots and systems lack the emotional skills that we as humans have, they are not intuitive.
There are many risks in using robots for health care, although, "health care" is a vague term, so I'll cover a few in general:
- Doctor/patient confidentiality is risked when using robots to handle personal medical matters, systems are never 100% secure.
- Robots and systems cannot emphasise with patients and will make decisions based on logic and theoretics, not emotionally - for example, if a patient is in a state of bad mental health, a robot will not be able to effectively analyse the right methods to take.
- The collection, storage and passing-on of patient information is risked as system encryption is never guaranteed.
