Answer:

Proxy Server

Explanation:

  • Proxy server is a server that acts as a mediator between two systems.
  • One system can be your computer and the other can be the server to which you are asking a service, such as requesting a web page.
  • Lets suppose you request a web page from a server and you type a URL of a website to access a web page.
  • This request goes to proxy server which sends this request on your behalf to the target server in order to retrieve that web page.
  • Proxy server makes this request to the target server on the internet by using one of its IP addresses.
  • When the proxy server gets that web page, it will forward that web page to your requesting computer.
  • If you request a specific service such as a website frequently the proxy server saves that website on its cache.
  • So if you request that website again, proxy server will forward it to you from its cache rather than requesting it again from the target server on your behalf resulting in quick response to the user's request. This speeds up the delivery of resources to the users.
  • Proxy servers provide users with privacy to access the websites, and they can surf the internet anonymously .

OUTER JOIN
select e.ID from employee e left outer join manages m on e.ID = m.ID
where m.manager_id is null;
NO OUTER
select e.ID from employee e where e.ID not in (select m.ID from manages m) or e.ID in (select m.ID from manages m where m.manager_id is null);

For two integers m and n, their GCD(Greatest Common Divisor) can be computed by a recursive function. Write a recursive method g
konstantin123 [22]

Answer:

In Python:

def gcd(m,n):

if n == 0:

 return m

elif m == 0:

    return n

else:

 return gcd(n,m%n)

Explanation:

This defines the function

def gcd(m,n):

If n is 0, return m

<em> if n == 0: </em>

<em>  return m </em>

If m is 0, return n

<em> elif m == 0: </em>

<em>     return n </em>

If otherwise, calculate the gcd recursively

<em> else: </em>

<em>  return gcd(n,m%n)</em>

<em />

<em>To call the function to calculate the gcd of say 15 and 5 from main, use:</em>

<em>gcd(15,5)</em>
