A. Long Comparisontime limit per test2 secondsmemory limit per test256 megabytesinputstandard inputoutputstandard outputMonocarp wrote down two numbers on a whiteboard. Both numbers follow a specific format: a positive integer x with p zeros appended to its end.Now Monocarp asks you to compare these two numbers. Can you help him?InputThe first line contains a single integer t (1 \le t \le 10^4) — the number of testcases.The first line of each testcase contains two integers x_1 and p_1 (1 \le x_1 \le 10^6; 0 \le p_1 \le 10^6) — the description of the first number.The second line of each testcase contains two integers x_2 and p_2 (1 \le x_2 \le 10^6; 0 \le p_2 \le 10^6) — the description of the second number.OutputFor each testcase print the result of the comparison of the given two numbers. If the first number is smaller than the second one, print '<'. If the first number is greater than the second one, print '>'. If they are equal, print '='.ExampleInput

NoteThe comparisons in the example are: 20 > 19, 1000 = 1000, 1999 < 2000, 1 = 1, 99 < 100.
