Answer #1

In order to traverse an implicit list in both the directions , we need Both header and footer. Header node represents the begining of the list while the footer node represents the ending of the list. If you have only one of these you can travese this list in one way only and the other way is not possible. So we need both the header and footer to traverse in both the directions.

    Consider an allocator on a 32-bit system that uses an implicit free list. Each memory block, either allocated or free, has a size that is a multiple of four bytes. Thus, only the 30 higher order bits in the header and footer are needed to record block size, which includes the header and footer and is represented in units of bytes. The usage of the remaining 2 lower order bits is as follows: bit 0 indicates the use of the...

    I need this in C++. This is all one question Program 2: Linked List Class For this problem, let us take the linked list we wrote in a functional manner in a previous assignment and convert it into a Linked List class. For extra practice with pointers we'll expand its functionality and make it a doubly linked list with the ability to traverse in both directions. Since the list is doubly linked, each node will have the following structure: struct...

    Contrast and compare elastic and inelastic collisions. Question 4 options: Both elastic and inelastic collisions have conservation of momentum if there are no outside forces. They are different in that elastic collisions bounce and inelastic collisions stick, and kinetic energy is conserved in inelastic collisions. They are basically the same thing, except the units are different. Elastic collisions do not have conservation of momentum and inelastic collisions have conservation of momentum if there are no outside forces. They are different...
