  • 第1题：

    A(71)is a data type whose major attributes are determined by the roles governing the insertion and deletion of its elements. The only element that can be deleted or removed is the one that was inserted most(72). Such a structure is said to have a last-in/first-out(LIFO)behavior, or protocol.

    A．stack

    B．queues

    C．pointer

    D．record
