Solution: Word Ladder

Explore how to apply breadth-first search to solve the Word Ladder problem by finding the shortest transformation sequence from a source word to a target word. This lesson helps you understand how to efficiently traverse words differing by one character using sets and queues, preparing you for coding interview challenges involving graph and string manipulation.

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 ( ...
