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
x₁, x₂, ..., 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 y₁, y₂, ..., 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 = 101111₂ = 47₁₀ = Y.

In the second sample, X = 102₃ = 21₅ and
Y = 24₅ = 112₃, thus
X < Y.

In the third sample, and
Y = 4803150₉. 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.
