Problem Description
MZL define F(X)
as the first ionization energy of the chemical element
X
Now he get two chemical elementsU,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 thatx≠y
Now he get two chemical elements
It is guaranteed that atomic numbers belongs to the given set:
It is guaranteed the two atomic numbers is either in the same period or in the same group
It is guaranteed that
Input
There are several test cases
For each test case,there are two numbersu,v ,means
the atomic numbers of the two element
For each test case,there are two numbers
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
