Hey there! Hello!
So, not sure if there's actually a button to "close out" a window to where you're able to reopen it again without having to go to where the file is located or go to recents in your application. Keep in mind that I'm on a MacBook, but I have worked on a Windows computer before.
One thing you can do is minimize the window. Your program will remain open, but your window will remain out of your way until you decide to expand it again. This seems to be the closest thing possible to your description, but if you had something else in mind, I'd love to hear more details.
This won't be a good solution if you're looking to cut down on the energy that certain programs may be taking up while open, even if you're not using them. But in terms of getting the windows off your desktop, minimizing is the way to go. It also allows you to have documents/windows out of the way while still being able to work on other documents/windows in the program (i.e. Microsoft Word, Google Chrome, Pages, etc.)
Hope this helped you out! Feel free to ask me any additional questions you may have. :-)
Answer:
word = input('Enter a single word: ', 's');
n = length(word);
nodupWord = [];
for i = 1:n
dup = false;
c = word(i);
for j = 1:i-1
if word(j) == c
dup = true;
break;
end
end
if ~dup
nodupWord = [nodupWord, c]; %add the non-duplicate char to end
end
end
disp(['Adjusted word: ', nodupWord])
Explanation:
The code is in Python.
Answer:
A and C
Explanation:
Option A:
In IPv6 there is a rule to reduce an IPv6 address when there are two or more consecutive segments of zeros just one time. This rule says that you can change the consecutive zeros for “::”
Here is an example
How to reduce the following IPv6 address?
ff02:0000:0000:0000:0000:0000:0000:d500
Ans: ff02::d500
Example 2:
2001:ed02:0000:0000:cf14:0000:0000:de95
Incorrect Answer -> 2001:ed02::cf14::de95
Since the rule says that you can apply “::” just one time, you need to do it for a per of zero segments, so the correct answer is:
Correct Answer -> 2001:ed02::cf14:0:0:de95
Or
2001:ed02:0:0:cf14::de95
Option C:
Since in IPv6 there are 
available addresses which means 340.282.366.920.938.463.463.374.607.431.768.211.456 (too many addresses), there is no need of NAT solution, so each device can have its own IP address by the same interface to have access through the internet if needed. If not, you can block the access through internet by the firewall.
