(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.

- What does the value of the top variable indicate in this ArrayStack implementation? What will happen if we call pop on this stack? What value will be returned, and what changes will occur in the array and the top variable? 3. If we push the value "echo" onto the stack, where will it be stored in the array, and what will be the new value of top? 4. Explain why index 0 contains the string "alpha" even though top is currently 3. 5. What would the state of the stack look like (values in the array and value of top) after two consecutive pop 0 operations?arrow_forwardPlease solve and show all work. Suppose there are four routers between a source and a destination hosts. Ignoring fragmentation, an IP datagram sent from source to destination will travel over how many interfaces? How many forwarding tables will be indexed to move the datagram from the source to the destination?arrow_forwardPlease solve and show all work. When a large datagram is fragmented into multiple smaller datagrams, where are these smaller datagrams reassembled into a single large datagram?arrow_forward

What is the advantage of web caches, and how does it work?arrow_forwardPlease solve and show steps. Consider a DASH system for which there are N video versions (at N different rates and qualities) and N audio versions (at N different rates and qualities). Suppose we want to allow the player to choose at any time any of the N video versions and any of the N audio versions. If we create files so that the audio is mixed in with its matched-rate video and the server sends only one media stream at a given time, how many files will the server need to store (each with a different URL)? If the server instead sends the audio and video streams separately and has the client synchronize the streams, how many files will the server need to store?arrow_forward
