哈哈，还得靠惊人的记忆力啊

Problem Description

        MZL define F(X) as the first ionization energy of the chemical element X

        Now he get two chemical elements U,V,given as their atomic number,he wants to compare F(U) and F(V)

        It is guaranteed that atomic numbers belongs to the given set:{1,2,3,4,..18,35,36,53,54,85,86}

        It is guaranteed the two atomic numbers is either in the same period or in the same group

        It is guaranteed that x≠y

Input

 There are several test cases

 For each test case,there are two numbers u,v,means the atomic numbers of the two element

Output

 For each test case,if F(u)>F(v),print "FIRST BIGGER",else print"SECOND BIGGER"

Sample Input

1 2
5 3

Sample Output

SECOND BIGGER
FIRST BIGGER
