　　2. 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 ions, if it is: 把一把顺序fo钥匙(24，49，13，20，59，23，90，35)插入进一种数据结构，这最初没有钥匙。在这些插入之后描绘数据结构，如果它是：

　　* a heap tree 一棵堆树

　　* an AVL tree AVL树

　　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.
