What will be the output of “hhhvv” using a file compression technique?

amhv

hhhvv



4a5m3h2v

4A5M3H2V

Explanation:

Compression techniques deal with removing redundancy in data to save memory space in computers.

In this case, there are runs of four A's, five M's, three H's and two V's, which is clear that each letter is repeated by some value. That is, there is redundancy in data: some values appear more than once.

Well, to save memory space in a computer, instead of having 4 + 5 + 3 +2 = 14 characters, we can reorder that by having only eight characters (4A5M3H2V), saving the same information using less memory space in a computer.

The former technique has a name. It is called Run-length encoding, and it is one of the most rudimentary compression techniques (Shotts, 2019) and also a lossless compression technique, that is, no data information is lost after the compression process.
