module AtCoder

    export readline

    function readline(T)
        return Base.parse(T, Base.readline(Base.stdin))
    end

end


module ABC162

    import Main.AtCoder
    export task_a

    function evaluate_task_a(target_integer::Core.Int64)
        return Base.in( target_integer, Base.digits( AtCoder.readline(Core.Int64) ) ) ? "Yes" : "No"
    end
    
    function execute_task_a()
        Base.println(evaluate_task_a(7))
    end

end


ABC162.execute_task_a()
