Consider you have a dictionary of unknown size. The size could be 10, or 1000 or 10^30. You are given a method- String GetWordAt(int index), which returns the word at 'index', or null if the index is invalid (or out of bounds).
How will you write a method that returns a boolean for a particular word look up? Boolean isWord(String word), returns true, if the dictionary contains the word, or false if it doesn't. Further constraint: Do this in O(log n) time. -- You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
