t=(int)(raw_input())

for i in range(t):

n=(int)(raw_input())

a=map(int,raw_input().split())

a.sort()

dic={}

i=0

for i in range(n):

p=a[i]

dic[p]=0

for i in range(n):

p=a[i]

dic[p]=dic[p]+1

max=1

r=a[0]

for key in dic:

if dic[key]>max:

max=dic[key]

r=key

print r,’ ',max

Here is my solution and I am getting a wrong answer though on my system it works perfectly well…please help!
