Valid Palindrome Made Easy | The Two-Pointer Trick

This video explains Valid Palindrome from the NeetCode 150 using the two-pointer technique. We cleanly compare characters from both ends of the string while ignoring spaces, punctuation, and letter casing. The two pointers move toward the centre until we find a mismatch or confirm that the string is a palindrome. I’m working through the NeetCode 150 as an average CS student and explaining each problem while learning the patterns behind it.
