def getCharacterForward(char, key): """ Given a character char, and an integer key, the function shifts char forward `key` steps

zhenek [66]

Answer:

def getCharacterForward(char, key):
charList = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
if(len(char) > 1):
return None
elif(not isinstance(key, int)):
return -1
else:
index = charList.find(char)
if(index + key <= 25):
return charList[index + key]
else:
return charList[(index + key)% 26]
print(getCharacterForward("C", 4))
print(getCharacterForward("X", 4))

Explanation:

Firstly, define a charList that includes all uppercase alphabets (Line 2). We presume this program will only handle uppercase characters.

Follow the question requirement and define necessary input validation such as checking if the char is a single character (Line 4). We can do the validation by checking if the length of the char is more than 1, if so, this is not a single character and should return None (Line 5). Next, validate the key by using isinstance function to see if this is an integer. If this is not an integer return -1 (Line 6 - 7).

Otherwise, the program will proceed to find the index of char in the charList using find method (Line 9). Next, we can add the key to index and use the result value to get forwarded character from the charList and return it as output (Line 11).

However, we need to deal a situation that the char is found at close end of the charList and the forward key steps will be out of range of alphabet list. For example the char is X and the key is 4, the four steps forward will result in out of range error. To handle this situation, we can move the last two forward steps from the starting point of the charList. So X move forward 4 will become B. We can implement this logic by having index + key modulus by 26 (Line 13).

We can test the function will passing two sample set of arguments (Line 15 - 16) and we shall get the output as follows:

G

B

What could be one possible reason where the recipient is not guaranteed that the data being streamed will not get interrupted?

anyanavicka [17]

Answer

The senders PC is using UDP protocol

Explanation

UDP is the User Datagram Protocol which is used as an alternative communication protocol to the TCP which is used primarily for establishing low latency and loss of tolerating connections between applications on the internet UDP is normally used by the programs running on different computers on a network. Its purposes is to send short messages which are datagrams. It is not much reliable because of its occasional loss of packet. Due to this packet loss the recipient is not guaranteed that the data being streamed will not get interrupted. This is because If a router on the Internet starts getting overloaded, or a packet gets corrupted due to interference or anything, the packet will be dropped unlike the TCP (Transmission control protocol)which resend the packets and keeps re sending. The UDP does not resend the packets which are dropped. Once they are dropped that all.
