Solution: Word Ladder

Explore how to implement the Word Ladder solution using breadth-first search to find the shortest transformation sequence between two words. Understand the process of checking adjacent words differing by one character, managing word sets for fast lookup, and tracking the sequence length. This lesson helps you grasp BFS applications in coding interviews for optimal tree traversal and pathfinding.

Statement

Given two words, src and dest, and a list, words, return the number of words in the shortest transformation sequence from src to dest. If no such sequence could be formed, return 00.

A transformation sequence is a sequence of words ( ...
