2505: A Math game

    Recently, Losanto find an interesting Math game. The rule is simple: Tell you a number H, and you can choose some numbers from a set {a₁,a₂,......,a_n}.If the sum of the number you choose is H, then you win. Losanto just want to know whether he can win the game.

    There are several cases.

    In each case, there are two numbers in the first line n (the size of the set) and H. The second line has n numbers {a₁,a₂,......,a_n}.

    If Losanto could win the game, output "Yes" in a line. Else output "No" in a line.
