Assignment 2: Ordered Word Ladders
An ordered word ladder ('owl') is an alphabetically-ordered sequence of words where each word in the sequence differs from its predecessor by one action:
changing one letter, e.g. barn→born
adding or removing one letter, e.g. band→brand and bran→ran
The following are examples of word ladders of different length:
ban→bar→boar→boat→goat, length 5
an→can→cane→dane→date→mate→mite→site→size, length 9
At the heart of the assignment is a function that compares 2 arbitrary strings and returns true if the strings satisfy one of the 2 conditions above, and false otherwise. This function has signature:
1 bool differByOne(char *, char *)
Write such a function and of course test it.
Details of the assignment will follow shortly.
