WebOct 1, 2024 · If the letter isn’t in this Trie’s lowest layer then we add a new dictionary at this level using that letter as the key. Then, we pass the dictionary (Trie) of our letter, the word, and the next index recursively back into this function. Using these two functions, we’d build the Trie shown above. But we have a problem. WebMar 23, 2024 · Going into the recursion, for each letter in the dictionary, if it is in the current position in the trie, add it to the list path, decrease its count and call _anagram from that current position. Coming out of the recursion, remove the letter from path and increment its count in letter_counts.
