Palindrome detection implements the same core insight — reverse and compare — across three data domains, each adapting the reversal mechanism to its representation: string slice reversal creates a full copy (O(n) space), integer half-reversal compares digits without string conversion (O(1) space), and linked list in-place reversal reuses existing nodes (O(1) space via mutation).
Three palindrome variants share reversal-comparison but adapt it to their data domain
Depends on (SL): palindrome-check-uses-slice-reversal, palindrome-num-half-reversal-technique, palindrome-ll-o1-space-via-mutation
