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 $x\neq y$

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"

1 2
5 3

SECOND BIGGER
FIRST BIGGER
