+Problem Statement
+Iroha loves Haiku. Haiku is a short form of Japanese poetry. A Haiku consists of three phrases with 5, 7 and 5 syllables, in this order.
 
+To create a Haiku, Iroha has come up with three different phrases. These phrases have A, B and C syllables, respectively. 
+Determine whether she can construct a Haiku by using each of the phrases once, in some order.
+
+Constraints
+1≦A,B,C≦10
+
+Input
+The input is given from Standard Input in the following format:
+A B C
+
+Output
+If it is possible to construct a Haiku by using each of the phrases once, print YES (case-sensitive). Otherwise, print NO.
+
+Sample Input 1
+5 5 7
+
+Sample Output 1
+YES
+Using three phrases of length 5, 5 and 7, it is possible to construct a Haiku.
