![]() ![]() Plus, we are doing this just once and then use it multiple times for unscrambling.Ģ. ![]() IMO this should take linear time wrt number of words as long as words have a small upper-bound on their length, say 10-12. For each word in dictionary, generate all permutations. Public static String swapStringIndexes(String s, int i, int j)ĭo_googles_bidding( 'elhloothtedrowl', sorted_dict, '')ġ. So we know that the sum and product of ordinals are invariant with respect to shuffling, but not with respect to changing the contents of the string. ![]() It's invariant to shuffling because of the associative property of addition and multiplication but not to changing the contents (see proof below). You can take advantage of the byte representations of the characters and make the key of your dictionary to be the tuple of (product,sum) of the integer representations of the bytes. ![]()
