Code Analysis and Problem Solving

Question $1$: Evaluating Programming Best Practices

Imagine a user asked the following request to an AI assistant:

"Please create a pseudocode function that will check if all the words in an array are palindromes. For example, an input of $[\text{'}$racecar$\text{'},$ 'noon', 'civic'$]$ should return True, but an input of $[\text{'}$racecar$\text{'},$ 'shoe', 'moon'$]$ should return False."

The following are three solutions that were returned by the AI:

Solution A

Solution B

Solution C

function reverse$\_$word$($string word$)$

reversed $=""$

for letter in word:

reversed $=$ letter $+$ reversed

return reversed

function check$\_$all$\_$palindromes$($array arr$)$

if arr$[0]==$ reverse$\_$word$($arr$[0])$

if arr$[1]==$ reverse$\_$word$($arr$[1])$

if arr$[2]==$ reverse$\_$word$($arr$[2])$

return true

return false

function reverse$\_$word$($string word$)$

reversed $=""$

for letter in word:

reversed $=$ letter $+$ reversed

return reversed

function is$\_$palindrome$($string word$)$

return word $==$ reverse$\_$word$($word$)$

function check$\_$all$\_$palindromes$($array arr$)$

for word in arr:

if is$\_$palindrome$($word$)==$ false

return false

return true

function reverse$\_$word$($string word$)$

reversed $=""$

for letter in word:

reversed $=$ letter $+$ reversed

return reversed

function check$\_$all$\_$palindromes$($array arr$)$

reversed$1=$ reverse$\_$word$($word$1)$

reversed$2=$ reverse$\_$word$($word$2)$

reversed$3=$ reverse$\_$word$($word$3)$

if arr$[0]$ does not equal reversed$1$:

return false

if arr$[1]$ does not equal reversed$2$:

return false

if arr$[2]$ does not equal reversed$3$:

return false

return
