Textbook Question
Chapter 1, Problem 1E
How does a computer’s main memory differ from its auxiliary memory?
Expert Solution & Answer

Explanation of Solution
Difference between main memory and auxiliary memory:
Main memory | Auxiliary memory |
It is directly accessible by the CPU. | It is not directly accessible by CPU |
It contains the data to be processed by the computer and holds the result of the calculations. | Data which needs to be stored permanently is kept in the secondary memory |
It is volatile in nature. | Auxiliary memory is non-volatile. |
It could be accessed by the data bus. | It could be accessed by the input-output channels. |
Data could be accessed in a faster rate. | Data accessed by the secondary memory is slower. |
It is made up of semiconductors | It is made of magnetic and optical material. |

(Dynamic Programming.) Recall the problem presented in Assign-
ment 3 where given a list L of n ordered integers you're tasked with removing m
of them such that the distance between the closest two remaining integers is maxi-
mized. See Assignment 1 for further clarification and examples. As it turns out there
is no (known) greedy algorithm to solve this problem. However, there is a dynamic
programming solution. Devise a dynamic programming solution which determines
the maximum distance between the closest two points after removing m numbers.
Note, it doesn't need to return the resulting list itself.
Hint 1: Your sub-problems should be of the form S(i, j), where S(i, j) returns
the maximum distance of the closest two numbers when only considering removing
j of the first i numbers in L. As an example if L [3, 4, 6, 8, 9, 12, 13, 15], then
S(4, 1) = 2, since the closest two values of L' = [3,4,6,8] are 6 and 8 after removing
4 (note, 8-6 =
= 2).

(Greedy Algorithms) Describe an efficient algorithm that, given a set
{x1, x2, . . ., xn} of points on the real line, determines the smallest set of unit-length
closed intervals that contains all of the given points. Argue that your algorithm is
correct.
