For example, in English, 'ascot' and 'tacos' are anagrams; so are 'tacos' and 'coats'. A set of words that are all anagrams of one another is an 'anagram set'. For example, ascot coast coats tacos is an anagram set. Letter case doesn't matter, so, for example, 'liberating' and 'Gilbertian' are considered to be anagrams. Write a program, 'make_anagrams', which reads in a list of words, one per line, and finds all the anagrams in the the word list. It should output an anagram dictionary, as follows: * 'Words' that contain digits or punctuational characters should be discarded. * Anagram sets that contain only one word should be omitted from the output. * If an anagram set contains two words, say 'halls' and 'shall', the output should contain two lines: halls shall shall halls * If an anagram set contains more than two words, the entire set should be listed under the alphabetically first word; the others should cross-reference it. For example: headskin nakedish sinkhead nakedish (See 'headskin') sinkhead (See 'headskin') * The output lines should be in alphabetic order. For example, if the input was 5th ascot ate carrot coast coats cots Dorian eat halls headskin inroad nakedish ordain Ronald's shall sinkhead tacos tea then the output should be: Dorian inroad ordain ascot coast coats tacos ate eat tea coast (See 'ascot') coats (See 'ascot') eat (See 'ate') halls shall headskin nakedish sinkhead inroad (See 'Dorian') nakedish (See 'headskin') ordain (See 'Dorian') shall halls sinkhead (See 'headskin') tacos (See 'ascot') tea (See 'ate') If you need a sample input, you may obtain English word lists from http://perl.plover.com/qotw/words/ If you prefer to do this quiz in a language other than English, please substitute whatever conventions are appropriate for that language.
