Question $1$: Evaluating Programming Best Practices

Imagine a user asked the following request to an $Al$ assistant: $[$racecar$\text{'},$ 'shoe', 'moon'$]$ should return False."

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

Solution A

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

reversed $=n$

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$\_$woord$($arr$[1])$

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

return true

return false

Solution B

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

Solution C

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
