北京社工“牵手计划”启动 形成对口支援、精准扶贫合力

百度 作为U23男足阵中最为大牌的球星，留洋德甲不莱梅队、转会费高达800万欧元、约合6千万元人民币的张玉宁，在U23亚洲杯后再度身披国字号战袍首发出战，但遗憾的是，这位国足红星依然没能打破自己漫长的球荒。

All elements (from a universal set) not in our set.

Example: With a universal set of {1,2,3,4,5,6}
the complement of {5,6} is {1,2,3,4}

The symbol is a little dash in the top-right corner.
Example: A' = {1,2,3,4}

Or a little "C" in the top-right corner.
Example: A^C = {1,2,3,4}

Together the set and its complement make the universal set.

Another Example, for the set below:
• the universal set is {alex, blair, casey, drew, erin, francis, glen, hunter, ira, jade}
• set S = {alex, casey, drew, hunter}
• the complement of set S is: S^C = {blair, erin, francis, glen, ira, jade}
