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
