The effect of the sudo iptables --policy INPUT DROP command is that it gives room for system administrators to handle incoming and outgoing traffic.
<h3>What does Sudo iptables -- policy input drop command do?</h3>
The iptables -P INPUT DROP is known to be an -P switch that places the default policy on any given chain.
When the default policy on the INPUT chain changes to DROP., it implies that an incoming packet did not match one set of the rules and as such, it will have to be dropped.

Answer:
b. <em>After each calculation within your program, insert a temporary statement that displays the most recently calculated value. When running your program, compare the displayed values with the expected values to identify where in the program the error is being introduced.</em>
Explanation:
Logging statements are an effective debugging technique. It is a good way of finding the location of faulty logic in a program.
One can trace the root problem through logging intermediary outputs.
We can find out from where the program is producing unexpected or unintended calculations, when their's a weird output logged.
Programs are series of instructions interpreted by a computer
- The description of the program is to compute the square of the difference between corresponding elements of two arrays
- The better version of the program is program A.
<h3>How to describe the programs</h3>
From the programs, we have the following highlights
- The program iterates from 1 to n - 1
- The iteration calculates the difference between corresponding elements of the arrays
- The difference is then squared
Hence, the description of the program is to compute the square of the difference between corresponding elements of two arrays
<h3>The better version</h3>
The better version of the program is program A.
This is so, because the program uses fewer instructions for the same task as program B
