What are the advantages and disadvantages of solving a problem that can be broken down into repetitive tasks with recursion as o

lesantik [10]

Answer:

Answered below

Explanation:

Recursion refers to the process of a function calling itself within its own definition. It calls itself repeatedly until a base condition is met and the loop breaks.

The advantages of recursion over loops include;

A) Recursion reduces time complexity.

B) Recursion is better at tree traversal and graphs.

C) Recursion reduces the time needed to write and debug code and also adds clarity to code.

Disadvantages of recursion include;

A) Recursion uses more memory because each function call remains in stack until the base case is met.

B) Recursion can be slow.

C) Recursion

Which of the following statements is true of satellite internet access?

MA_775_DIABLO [31]

Answer:

So, to get a more simplified version of the question, we will now assemble all the statements and one by one describe them.

Explanation:

Satellite internet is obviously not the slowest forms of access, And its more expensive to connect to.
Yes, satellite access do provide access to remote rural areas.And they require a system of antennas in order to connect from the earth to the satellite which is providing the services.
Yes satellites internet works by sending and receiving messages or data required via a transmitter and receiver antenna, which connects the users device to the satellite providing the services.
The satellite internet do cover a very large portion of Earths surface as there are now many number of satellites sent to the space which has made the communication system more fast and convenient to use.

Using the computational knowledge in python it is possible to write a code that Given a name and a Python list of Cow objects

<h3>Writting the code in python:</h3>

A top level class may have only the following accessmodifier.

GREYUIT [131]

Answer: Public

Explanation:

A top level class can have a public, as top level cannot be private and protected because the modifier private is not allowed. As, top level is a class which is not a nested class. Interface of a access modifier is either public or no modifier. There are two types of access control modifier are top level - public and member level- private, protected.
