问题 单项选择题

栈和队列的共同点是______。

A.都是先进后出

B.都是先进先出

C.只允许在端点处插入和删除元素

D.没有共同点

答案

参考答案:C

解析:[知识点] 线性表的概念[评析] 栈和队列都是一种特殊的操作受限的线性表,只允许在端点处进行插入和删除。二者的区别是:栈只允许在表的一端进行插入或删除操作,是一种“后进先出”的线性表;而队列只允许在表的一端进行插入操作,在另一端进行删除操作,是一种“先进先出”的线性表。

Can 13-year-olds do something to change the world? Cris Kesz Valdez, 13, from the Philippines believes so.

At the age of 7, Valdez set up an organization to give homeless kids things like slippers and toothbrushes. So far he has helped more than 10,000 children improve their lives in his hometown.

Valdez won the 2012 International Children’s Peace Prize on September 19, 2012.

“My motto is ‘we can change the world one heart at a time,’ ” Valdez said at the award ceremony.

In fact, Valdez is a homeless kid himself. He looked for food from trash, lived on the streets and slept in a public cemetery for most of his childhood. His parents didn’t care about him and often beat him. Valdez said he felt he was living in “darkness” at that time.

But this “darkness” didn’t turn him into a dark person. Valdez got help from community workers. On his first birthday party, at the age of 7, Valdez decided what he wanted most was to help other children who were still living on the streets.

“I didn’t have a lot of money, but I had a lot of love to give,” Valdez explained.

That day was the birth of the organization, Championing Community Children. Since then, Valdez and his friends visit homeless children and hand out bags with slippers, toys and even candy. They nurse their wounds, teach them about their rights and offer them hope.

“I want children on the streets to get the same chance as I have,” he said.

5.计算比准价格
将交易实例中的地价和待估宗地与比较实例的因素修正系数代入计算公式,则比准地价A=3445×(108/104)×(100/96)×(100/98)×(100/104)×(100/96)
=3808.71(元/m2)
比准地价B=3510×(108/100)×(100/96)×(100/102)×(100/98)
=3950.33(元/m2)
比准地价C=3880×(108/107)×(100/99)×(100/92)×(100/98)
=4387.56(元/m2)
通过对上述三个比准价格的分析比较,确定单位土地面积地价为
(3808.71+3950.33+4387.56)/3=4048.87(元/m2)

请根据以上情况,回答下列问题


比较案例中,有挂牌出让案例,并且没有对挂牌方式进行价格修正,是否合理为什么试比较一般情况下土地挂牌出让与土地转让交易在市场环境方面的不同。
