题目:

设有一个双向链表h,每个结点中除有prior、data和next共3个域外,还有一个访问频度域freq,在链表被起用之前,每个结点中的freq域的值均被初始化为零。每当进行LocateNode(h,x)运算时,令元素值为x的结点中freq域的值加1,并调整表中结点的次序,使其按访问频度的递减序列排序,以便使频繁访问的结点总是靠近表头。试写一符合上述要求的LocateNode运算的算法。

Future and Today
  It is well known that everyone has his own dream as well as his own future. But do you know what future really is ? I have to say that future is now. That is to say we must treasure every minute now. If we want to have a bright future, we should know how important time is and use it well.
  There is an old English saying: "Gain time, gain life." Then what's time? Time is something that we can't see or touch, but we can feel it passing by. Time is always with us. When we are at table, time passes; when we play, time goes by unnoticeable. We always say "Time is money", but time is even more precious(珍贵的)than money, because when money is spent , we can earn it back. But if time is gone away, it will never return. So, some of us even say time is priceless(无价的).
  We should always remember: future is now. For us students, we should try our best to work hard in order to create a great future of our own. We should make the best use of every hour and be the master of today. We should do everything before us as well as possible. And never put off what can be done today till tomorrow.
  As we all know , "Time and tide wait for no man." If you waste today, you will regret tomorrow. So from now on, work hard. Tomorrow will be better, and your future will be brighter .Remember: "No pains, no gains." Today's hard work is the cause of tomorrow's harvest.
