Eyad was given a simple math problem, but since he is very bad at math he asked you to help him.

Given 4 numbers, a, b, c, and d. Your task is to find whether a^b is less than c^d or not.

It is guaranteed that the two numbers above are never equal for the given input.

Input

The first line contains an integer T (1 ≤ T ≤ 10⁵), where T is the number of test cases.

Then T lines follow, each line contains four integers a, b, c, and d (1 ≤ a, b, c, d ≤ 10⁹).

Output

For each test case, print a single line containing "<" (without quotes), if a^b is less than c^d. Otherwise, print ">" (without quotes).
