All the words in wordlist are unique. this approach leverages breadth first search (bfs), where each word is a node in the graph, and an edge exists between two nodes if they differ by exactly one letter. the goal is to find the shortest path from beginword to endword. Given two words, beginword and endword, and a dictionary wordlist, return the number of words in the shortest transformation sequence from beginword to endword, or 0 if no such sequence exists. Leetcode solutions in c 23, java, python, mysql, and typescript. Create two queues, q1 and q2, for "start > end" and "end > start" search directions, respectively. create two hash maps, m1 and m2, to record the visited nodes and their corresponding expansion times (steps). during each search, prioritize the queue with fewer elements for search expansion.
