Problem Description
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
F(u)>F(v),print "FIRST BIGGER",else print"SECOND BIGGER"
Sample Input
1 2 5 3
Sample Output
SECOND BIGGER FIRST BIGGER
