Answer:
The program in Python is as follows:
word = input("Word: ")
if len(word) < 5:
print("At least 5 characters")
else:
pal = word[0:5]
word = word[0:4]
word = word[::-1]
pal+=word
print(pal)
Explanation:
This gets the word from the user
word = input("Word: ")
This checks if the length of the word is less than 5.
if len(word) < 5:
If yes, this tells the user that at least 5 characters is needed
print("At least 5 characters")
If otherwise
else:
This extracts the first 5 characters of the word into variable named pal
pal = word[0:5]
This extracts the first 5 characters of the word into variable named word
word = word[0:4]
This reverses variable word
word = word[::-1]
This concatenates pal and word
pal+=word
This prints the generated palindrome
print(pal)
You could assign values to variables and break it up into if else-if else statements.
<span>Pseudocode:</span>
if a < b and b < c:
print("increasing")
else if a > b and b > c:
print("decreasing")
else:
print("neither")
Hope this helps.

Answer:
There could be a collision if a hidden node problem occurs.
Explanation:
CSMA/CA(carrier sense multiple access/ collision avoidance) is a multiple access method in wireless networking, that allows multiple node to transmit. Collision avoidance of this method is based on preventing signal loss or downtime as a result of collision of transmitting multi signals.
If a node at step 4(transmit frame) sends the first frame, the node still needs to send a RTS(request to send) and to receive a Clear to send (CTS) from the WAP, the is to mitigate the issue of hidden node problem as all frame are treated as unit, so other listening nodes, not detected would seek to connect and transmit as well.
