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
