pub fn part2(input: &str) -> String

Finally, the standard way to represent a Knot Hash is as a single hexadecimal string; the final output is the dense hash in hexadecimal notation. Because each number in your dense hash will be between 0 and 255 (inclusive), always represent each number as two hexadecimal digits (including a leading zero as necessary). So, if your first three numbers are 64, 7, 255, they correspond to the hexadecimal numbers 40, 07, ff, and so the first six characters of the hash would be 4007ff. Because every Knot Hash is sixteen such numbers, the hexadecimal representation is always 32 hexadecimal digits (0-f) long.

Here are some example hashes:

• The empty string becomes a2582a3a0e66e6e86e3812dcb672a272.

assert_eq!(part2(""), "a2582a3a0e66e6e86e3812dcb672a272");

• AoC 2017 becomes 33efeb34ea91902bb2f59c9920caa6cd.

assert_eq!(part2("AoC 2017"), "33efeb34ea91902bb2f59c9920caa6cd");

• 1,2,3 becomes 3efbe78a8d82f29979031a4aa0b16a9d.

assert_eq!(part2("1,2,3"), "3efbe78a8d82f29979031a4aa0b16a9d");

• 1,2,4 becomes 63960835bcdc130f0b66d7ff4f6a5a8e.

assert_eq!(part2("1,2,4"), "63960835bcdc130f0b66d7ff4f6a5a8e");
