Question

Write a function named isPalindrome that accepts a string parameter and returns true if that string is a palindrome, or false if it is not a palindrome. For this problem, a palindrome is defined as a string that contains exactly the same sequence of characters forwards as backwards, case-insensitively.

Answer 1

The isPalindrome function determines whether a given string is a palindrome by comparing the original string's lower case form to its reversed lower case form, returning true if they match.

Step-by-step explanation:

Function to Check for Palindrome Strings

The function isPalindrome is designed to check if a provided string is a palindrome. A palindrome is a string that reads the same forwards and backwards, ignoring case sensitivity. To determine this, the function can convert the string to lower case, reverse it, and then compare it to the original lower case version of the string. If the two are identical, it returns true, indicating the string is a palindrome. Otherwise, the function returns false.

An example implementation in Python could look like this:

def isPalindrome(s):
sLower = s.lower()
return sLower == sLower[::-1]

This code snippet converts the string to lower case, then relies on the slicing method to reverse the string and compare it with its original lower case form.
