先对狼人进行枚举，之后再验证是否正确

python版本

def solve():
    for i in range(1,n):
        for j in range(i + 1,n + 1):
            num = 0
            LangH = 0
            for k in range(1,n+1): #枚举说辞
                if abs(board[k]) == i or abs(board[k]) == j:  #说狼的
                    if board[k] > 0 : #说谎
                        num += 1
