// We're reading years from standard input, one year per line, outputting
// years from the sexagenary cycle [1]. This is slightly more than what
// the challenge ask; the challenge asks to output the heavenly stem [2],
// and the earthly branch [3]. But we also output its Yin/Yang.

//

//
// Each of the cycles have been rotated so the first entry corresponds to
// the year 0 in the Proleptic Gregorian calendar. (We're using the
// convention of having a year 0, as per ISO 8601).
// That way, we can just mod the year with the number of entries, without
// first having to subtract something from the year.
//
// The heavenly stems last for 2 years, so we just duplicate the entries.
