Interview Prompt
We've got a start word, an end word, and a list of allowed words. Find the shortest way to turn the start word into the end word by changing one letter at a time, where every word you pass through along the way is in the list, and return how many words are in that shortest chain.
Summary
One small step at a time can cover a great distance.
