( 4540 ) A Bus Game PROGRAMMING greedy 1300

After Fox Ciel won an onsite round of a programming contest, she took a bus to return to her castle. The fee of the bus was 220 yen. She met Rabbit Hanako in the bus. They decided to play the following game because they got bored in the bus. Determine the winner of the game. The first line contains two integers x (0 ≤ x ≤ 106) and y (0 ≤ y ≤ 106), separated by a single space. If Ciel wins, print "Ciel". Otherwise, print "Hanako". In the first turn (Ciel 's turn), she will choose 2 100-yen coins and 2 10-yen coins. In the second turn (Hanako 's turn), she will choose 1 100-yen coin and 12 10-yen coins. In the third turn (Ciel 's turn), she can 't pay exactly 220 yen, so Ciel will lose.
