Given two integers, a and b, you should check whether a is divisible by b or not. We know that an integer a is divisible by an integer b if and only if there exists an integer c such that a = b * c.
Input starts with an integer T (≤ 525), denoting the number of test cases.
Each case starts with a line containing two integers a (-10^{200} ≤ a ≤ 10^{200}) and b (|b| > 0, b fits into a 32 bit signed integer). Numbers will not contain leading zeroes.
For each case, print the case number first. Then print 'divisible' if a is divisible by b. Otherwise print 'not divisible'.
