MZL's chemistry

Time Limit: 2000/1000 MS (Java/Others)    Memory Limit: 65536/65536 K (Java/Others)
Total Submission(s): 373    Accepted Submission(s): 310

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

百度第一电离能，然后打个表就好
