Answer:
While loops are typically used when you don’t know how many times the loop needs to repeat. The body of the loop will repeat while the condition is true. The logical expression will be evaluated just before the body of the loop is repeated.
Let’s say that we want to find the square root of a number. For some square roots, you’re never going to be exact. Let’s say that we want to find a square root that, when multiplied by itself, is within 0.01 of the square we want. How do we do it? There’s a really old process that we can apply here.
Start by guessing 2.
Compute the guess squared.
Is the guess squared close to the target number? If it’s within 0.01, we’re done. We’ll take the absolute value of the difference, in case we overshoot. (In Python, abs is the absolute value function.)
If it’s not close enough, we divide the target number by our guess, then average that value with our guess.
That’s our new guess. Square it, and go back to Step #3.

Answer:
Explanation:
Let's do this in Python, first we need to convert the number into string in order to break it into a list of character, then we can replace the kth character with d. Finally we join all characters together, convert it to integer then output it
def setKthDigit(n, k, d):
n_string = str(n)
d_char = str(d)
n_char = [c for c in n_string]
n_char[k] = d_char
new_n_string = ''.join(n_char)
return int(new_n_string)
Answer:
True of False?
True
Explanation:
Different sub domains can be directed to different IPs servers but a client server cannot be forced to keep looking at name servers for additional records.
To delegate a subdomain to a zone on another server, one would need to add NS-records for the sub-domain name. This would point to the host names of the DNS servers hosting the sub-domain - in the parent zone.
In the "DNS records" window right-click the parent zone in the left list and select "New NS-record":
