The
accessibility category of apps makes the computer easier for blind people to
use. In general the accessibility apps are apps that help people with
disabilities use a particular piece of hardware. For example there is an app
designed to help blind people use their devices by paring them with a voluntary
non-blind people trough audio-video connections.
Answer:
Let L and R be the sub-trees underneath the root r.
If the height of L (where we consider height to be the maximum length of all root-leaf paths) is ∆ more than that of R, ∆ ≥ 0, then the length of the edge (r, R) is increased by ∆.
Then, we separately perform the same cycle over L and R.
Once more, by induction, argue that this greedy algorithm is efficient –
when it does not increase the length of (r, R) edge by ∆, then prove that the solution can be improved.
Answer:

It is used for storing data and information.
Answer:
The maximum value that are represented as unsigned n -bit binary integer is 
. The unsigned binary integer refers to the fixed point of the system that does not contain any fractional digits.
The unsigned binary integer contain module system with the power 2. The number of student table in the class is the best example of the unsigned integer. The numbers can be represented by using the binary notation and bits in the computer system.
