Assignment 2: Word Ladder
A word ladder is a sequence of words
- which are in alphabetic order
- each word in the sequence differs from its predecessor by
changing one letter, e.g. born→barn
adding or removing one letter, e.g. band→brand
The following are examples of word ladders of different length (that could each easily be made longer):
big→bit→bat→boat, length 4
cold→cord→word→ward→warm, length 5
line→fine→five→dive→live→like→lake→take→bake→cake→fake, length 11
