1 3 5

SAMPLE OUTPUT

Explanation

Number of test cases=2
1st test case, number of elements =5 
Best numbers are  2 , 4 ; frequency=2
2nd test case, number of elements =3
No Best numbers
for p in range(input()):
	input()
	l=map(int,raw_input().split())
	print sum([l.count(i) for i in set(l) if i%2==0])
