个网址的数据。
14通过7并将每个URL作为矢量存储，并在google.com gmail.com
google.com maps.com
facebook.com ufl.edu
ufl.edu google.com
ufl.edu gmail.com
maps.com facebook.com
gmail.com maps.com
中仅打印这样的唯一矢量：
cin到目前为止，我已经完成了以下代码，但未打印c++。
1 google.com
2 gmail.com
3 facebook.com
4 maps.com
5 ufl.edu

根据您的输入约束始终是固定的。输入共有7行，每行包含2个网址。因此，总的来说，我们必须扫描14个网址作为字符串。并且，为了查找唯一的字符串，我们可以使用@(
Html.Kendo().DropDownList()
.Name("Type")
.DataTextField("Text")
.DataValueField("Value")
.OptionLabel("---Select Partner---")
.HtmlAttributes(new { data_value_primitive = "true" })
.BindTo(ViewBag.TemporaryPartnersList)
.Value("1")
)
来存储url，并且只有在hashMap中不存在的情况下，才能将url插入向量中。总体代码为：
hashMap
