Solution: Word Ladder

Explore how to solve the shortest word ladder problem by applying Breadth-First Search. Understand how to efficiently traverse through word transformations and return the length of the shortest sequence from source to destination. This lesson helps you implement BFS for string manipulation problems common in coding interviews.

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 ((src \to word1word_1 \to word2word_2 ...
