The question in an interview. And I got lost with this one. Could you guys give some algorithm or idea on this ?
Write a program that reads a large list of English words (e.g. from / usr/share/dict/words on a unix system) into memory, and then reads words from stdin, and prints either the best spelling suggestion, or "NO SUGGESTION" if no suggestion can be found. The program should print ">" as a prompt before reading each word, and should loop until killed. Your solution should be faster than O(n) For example: > sheeeeep sheep > peepple people > sheeple NO SUGGESTION The class of spelling mistakes to be corrected is as follows: Case (upper/lower) errors: "inSIDE" => "inside" Repeated letters: "jjoobbb" => "job" Incorrect vowels: "weke" => "wake" Any combination of the above types of error in a single word should be corrected (e.g. "CUNsperrICY" => "conspiracy"). If there are many possible corrections of an input word, your program can choose one in any way you like. It just has to be an English word that is a spelling correction of the input by the above rules. Final step: Write a second program that *generates* words with spelling mistakes of the above form, starting with correctly spelled English words. Pipe its output into the first program and verify that there are no occurrences of "NO SUGGESTION" in the output -- You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
