Yes

Solution in Julia (1.4.0) (judge verdict: Accepted)

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 task_a(target_integer::Core.UInt16)

  		given_integer = AtCoder.readline(Core.UInt16)
  		data_digits   = Base.digits(given_integer)
  
  		for itr = 1:1:Base.size(data_digits, 1)
    		if (data_digits[itr] == target_integer)
      			return "Yes"
    		end
  		end

  		return "No"

	end

end

Base.println(ABC162.task_a(Base.convert(Core.UInt16, 7)))
