Given an integer N and list of D hexadecimal digits, what is the smallest positive integer X, whose representation in base 16 consists only of given digits, such that X is divisible by N?
The first line of the input file starts with the integer T, the number of test cases (1 ≤ T ≤ 100). Each test case consists of two lines, in the following format:
N D d1 d2 . . . dD
N(1 ≤ N ≤ 200, 000) and D(1 ≤ D ≤ 16) are as described in the problem statement (both given here in base 10) and di(1 ≤ i ≤ D) are heximal digits allowed to be used in the result. You can assume that digits are sorted.
For each test case, output the smallest positive number X in base 16 such that X is divisible by N and it contains only digits provided. If there is no such number, output ”no solution” instead.
