The second line contains N face values of the coins, which is all positive numbers no more than 500. All the numbers in a line is separated by a space.

Output Specification:

For each test case, print in one line the both face values V1 and V2 (separated by a space) such that V1 + V2 = M and V1 &l T;= V2. If Such a solution is not unique, the output of the one with the smallest V1. If There is no solution, output "no solution" instead.
