Leetcode 127. word ladder explanation for leetcode 127 word ladder, and its solution in python. Given two words, beginword and endword, and a dictionary wordlist, return the number of words in the shortest transformation sequence frombeginwordtoendword, or 0 if no such sequence exists. Given two words (beginword and endword), and a dictionary's word list, find the length of shortest transformation sequence from beginword to endword, such that: only one letter can be changed at a time. each transformed word must exist in the word list. note that beginword is not a transformed word. note:. Leetcode 127. word ladder leetcode problems word ladder difficulty: hard key point: bfs (shortest path) word transformation this is a classic shortest path problem on an implicit graph. each word is a node, and an edge exists if two words differ by exactly one letter.
