Solution: Word Ladder

Explore how to solve the Word Ladder problem by applying Tree Breadth-First Search (BFS). This lesson guides you to understand and implement an algorithm that finds the shortest transformation sequence from a source word to a destination word by changing one character at a time, using efficient data structures like sets and queues.

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 ( ...
