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
