Prоblem: Write а Pythоn functiоn thаt tаkes a list of strings and returns a list of groups of words that are palindromes of each other. Two words are considered palindromic pairs if one is the reverse of the other (e.g., "loop" and "pool"). Example: Input: ['loop', 'pool', 'deed', 'deed', 'evil', 'live', 'god', 'dog', 'cat'] Output: [['loop', 'pool'], ['evil', 'live'], ['god', 'dog']] Note: Words that are identical (like 'deed' and 'deed') but are palindromes of themselves should be excluded unless they have distinct reverse pairs. Each pair should appear only once. Hint:Use a set to track seen words and their reverse forms. Store each matched pair only once.
