I suppose you could use a stack but you could also use two pointers at each end of the string to compare corresponding characters and if equal move the pointers in the direction of the center of the string. When all characters match (spaces and punctuation are not characters) and the pointers are equal, then you have a palindrome.

I've always written a recursive function to determine if a phrase is a palindrome, but it might be overkill to use a recursive function when weaknessforcats' method works nearly exactly the same way.
