          Given two numbers A and B, find Kth digit from right of AB.

            Input:
            The first line of the input contains T denoting the number of test cases. T testcases follow.  Each of the next T lines contains three space separated positive integers denoting the value of a , b and k respectively.

            Output:
            For each test case, in a new line, output the Kth digit from right of AB in new line.

            Constraints:
            1 <= T <= 100
            1 <= A , B <=15
            1 <= K <= |totaldigits in AB|

            Example:
            Input:
            2
            3 3 1
            5 2 2
            Output:
            7
