After seeing the "ALL YOUR BASE ARE BELONG TO US" meme for the first time, numbers X and Y realised that they have different bases, which complicated their relations. You're given a number X represented in base b x and a number Y represented in base b y . Compare those two numbers. The first line of the input contains two space-separated integers n and b x ( 1 ≤ n ≤ 10 , 2 ≤ b x ≤ 40 ), where n is the number of digits in the b x -based representation of X . The second line contains n space-separated integers x 1 , x 2 , ..., x n ( 0 ≤ x i < b x ) — the digits of X . They are given in the order from the most significant digit to the least significant one. The following two lines describe Y in the same way: the third line contains two space-separated integers m and b y ( 1 ≤ m ≤ 10 , 2 ≤ b y ≤ 40 , b x ≠ b y ), where m is the number of digits in the b y -based representation of Y , and the fourth line contains m space-separated integers y 1 , y 2 , ..., y m ( 0 ≤ y i < b y ) — the digits of Y . There will be no leading zeroes. Both X and Y will be positive. All digits of both numbers are given in the standard decimal numeral system. Output a single character (quotes for clarity): ' < ' if X < Y ' > ' if X > Y ' = ' if X = Y In the first sample, X = 101111 2 = 47 10 = Y . In the second sample, X = 102 3 = 21 5 and Y = 24 5 = 112 3 , thus X < Y . In the third sample, and Y = 4803150 9 . We may notice that X starts with much larger digits and b x is much larger than b y , so X is clearly larger than Y .
