[说明] 设有一个带头结点的双向循环链表L，每个结点有4个数据成员：指向前驱结点的指针prior、指向后继结点的指针next、存放数据的成员data和访问频度freq。所有结点的freq初始时都为0。每当在链表上进行一次L.Locate(x)操作时，令元素值x的结点的访问频度freq加1，并将该结点前移，链接到现在它的访问频度相等的结点后面，使得链表中所有结点保持按访问频度递减的顺序排列，以使频繁访问的结点总是靠近表头。 [函数] void Locate(int ＆x) ＜结点类型说明＞ p=first-＞next; while(p!=first ＆＆ (1) )p=p-＞next; if(p!=first) (2) ; ＜结点类型说明＞ current=p; current-＞prior-＞next=current-＞next; current-＞next-＞prior=current-＞prior; p=current-＞prior; while(p!=first ＆＆ (3) )p=p-＞prior; current-＞next= (4) ; curren-＞prior=p; p-＞next-＞prior=current; p-＞next= (5) ; else printf("sorry.Not find! \n");

In a democratic society citizens are encouraged to form their own opinions on candidates. The opinions held by any population are shaped and controlled by several factors: individual circumstances, the mass media, special interest groups, and opinion leaders. Wealthy people tend to think differently on social issues from poor people. Factory workers probably do not share the same views as white-collar workers. Women employed outside their homes sometimes have perspectives different from those of fulltime homemakers. In these and other ways individual status shapes one’’s view of current events. The mass media, especially television, are powerful influences on the way people think and act. Government officials realize that the public tends to "follow the headlines". Whatever is featured in newspapers and magazines and on television attracts enough attention. The mass media have also created larger audiences for government and a wider range of pubic issues than existed before. Prior to television and the national editions of newspapers, issues and candidates tended to remain localized. Today’’s elections are seen as struggles between party leaders and programs. In the United States radio and television have been beneficial to the presidency. Since the days of Franklin D. Roosevelt and his "fireside chats", presidents have appealed directly to a national audience over the heads of Congress to advocate their programs. Special groups spend vast money annually trying to influence public opinion. Public utilities, for instance, tried to sway public opinion in favor of nuclear power plants. Opposed to them were citizens’’ organizations that persuaded to halt the use of nuclear power. Opinion leaders are usually such prominent public figures as politicians, show business personalities, and celebrity athletes. The opinions of these individuals, whether informed and intelligent or not, carry weight with some segments of the population. Some individuals, such as Nobel Prize winners, are suddenly thrust into public view by the media. By quickly reaching a large audience, their views gain a hearing and are perhaps influential in shaping views on complex issues. It is obvious that the opinion of famous people______.

A. is often ignored by the public
B. is seldom expressed to the point
C. is often imposed on the public
D. usually has a strong influence on people
