Scottish Highers Computing Science Software Design and Development-Implementation: A word is a palindrome if it rea

Question

A word is a palindrome if it reads the same backwards as forwards, for example:

mum, noon, madam, kayak, racecar

A program identifies if a word is a palindrome by checking if the first and last characters are the same. If they are, it then checks the second and second last characters and so on.

The incomplete program is shown below.

Line 1 FUNCTION checkPalindrome(STRING word) RETURNS BOOLEAN
Line 2 DECLARE left INITIALLY 0
Line 3 DECLARE right INITIALLY length(word) - 1
Line 4 DECLARE validPalin INITIALLY TRUE
Line 5 WHILE left < right AND
Line 6 IF word[left] = word[right] THEN
Line 7 SET left TO left + 1
Line 8 SET right TO right - 1
Line 9 ELSE
Line 10 SET validPalin TO FALSE
Line 11 END IF
Line 12 END WHILE
Line 13 RETURN validPalin
Line 14 END FUNCTION
…

RECEIVE userWord FROM KEYBOARD
Line 26

(a) Using a programming language of your choice, complete Line 5 below.

WHILE left < right AND

(b) Using a programming language of your choice, write the missing code at Line 26 to call the function.
