Gennady owns a small hotel in the countryside where he lives a peaceful life. He loves to take long walks, watch sunsets and play cards with tourists staying in his hotel. His favorite game is called 「Mau-Mau」.
To play Mau-Mau, you need a pack of 52cards. Each card has a suit (Diamonds — D, Clubs — C, Spades — S, or Hearts — H), and a rank (2, 3, 4, 5, 6, 7, 8, 9, T, J, Q, K, or A).At the start of the game, there is one card on the table and you have five cards in your hand. You can play a card from your hand if and only if it has the same rank or the same suit as the card on the table.In order to check if you’d be a good playing partner, Gennady has prepared a task for you. Given the card on the table and five cards in your hand, check if you can play at least one card.

Input
The first line of the input contains one string which describes the card on the table. The second line contains five strings which describe the cards in your hand.Each string is two characters long. The first character denotes the rank and belongs to the set {2,3,4,5,6,7,8,9,T,J,Q,K,A} The second character denotes the suit and belongs to the set {D,C,S,H}
All the cards in the input are different.

Output
If it is possible to play a card from your hand, print one word 「YES」. Otherwise, print 「NO」.
You can print each letter in any case (upper or lower).

Note
In the first example, there is an Ace of Spades (AS) on the table. You can play an Ace of Diamonds (AD) because both of them are Aces.In the second example, you cannot play any card.In the third example, you can play an Ace of Diamonds (AD) because it has the same suit as a Four of Diamonds (4D), which lies on the table.

題意：桌上有一張紙牌，只有當你手上五張紙牌中任意一張紙牌的花色與數字其中一項與之相同你就能夠打出一張手牌，判斷可否打出一張手牌。

思路：字符數組匹配，只要有一個字符相同就能夠輸出YES.
