　　以下收集的題目是揚(yáng)智科技筆試環(huán)節(jié)最�？嫉模隳茏鰧Χ嗌倌�？大家也來練一練吧！
　　1. Insert a sequence fo keys(24,49,13,20,59,23,90,35) into a data structure, which has no keys initially. Depict the data structure after these insertions, if it is:

　　* a heap tree

　　* an AVL tree

　　2. Queue is a useful structure

　　* What is a queue?

　　* Write 5 operations or functions, without details, that can be done on a queue.

　　3. * What is a synchronous I/O bus?

　　* What is an asnchronous I/O bus?

　　* Compare the advantages and disadvantages of synchronous and a synchronous I/O bus.

　　4. Explain the following terminology:

　　* Baud rate

　　* Handshaking

　　* Memory mapped I/O

　　5. Explain the key issues in supporting a real-time operation system for embedded system.

　　6. Explain the mapping of visual addresses to real addresses under paging by

　　* direct mapping

　　* associative mapping

　　* combined direct/associated mapping

　　7. Please explain what is “write-back” and “write-through”, and discuss the advantage and disadvantage about these two methods.

　　8. Explain the concept and benefit of threads

　　9. What is hardware interrupt? What is software interrupt? What is exception? Please tell me all you know about interrupt.

　　10. Write a recursive function that tests wether a string is a palindrome. A palindrome is s string such as “abcba” or “otto” that reads the same in both directions.If you can write this function recursively,you can write an iterative version of this function instead.

　　15.驅(qū)動程序的BUFFER能swap到磁盤上去嗎?為什么?

　　16.試編寫3個函數(shù)實(shí)現(xiàn)

　　(1)建立一個雙向鏈表

　　(2)插入一個節(jié)點(diǎn)

　　(3)刪除一個節(jié)點(diǎn)

　　17.簡述Hardware interrupt和software中斷的區(qū)別，簡述其應(yīng)用。

　　18.試編寫一個函數(shù)，計算一個字符串中A的個數(shù)。

　　19.畫出其相應(yīng)流程圖并編寫一個函數(shù)實(shí)現(xiàn)一個整數(shù)到二進(jìn)制數(shù)的轉(zhuǎn)換，如輸入6，輸出110。
