A word is an abc word if the order of the indices of 'a', 'b' and 'c' and the final letter of the word are unchanged by sorting. (The index of 'a' would be the length of the word -- one greater than the last index into the word -- if 'a' was missing from the word. So by including that last index in our list of indices to be sorted, we eliminate all words which are missing an 'a', 'b' or 'c'.)<lang J> >(#~ (-: /:~)@(<:@#,~i.&'abc')@>) cutLF tolower fread 'unixdict.txt'
