The programmer intended the following pseudocode to get five sets of two numbers each, calculate the sum of each set, and calculate the sum of all the numbers entered. It will not function as intended, however. Find the error.
// This
Declare Integer number, sum, total
Declare Integer sets, numbers
Constant Integer MAX_SETS = 5
Constant Integer MAX_NUMBERS = 2
Set sum = 0;
Set total = 0;
For sets = 1 To MAX_NUMBERS
For numbers = 1 To MAX_SETS
Display "Enter number ", numbers, " of set ", sets, "."
Input number ;
Set sum = sum + number
End For
Display "The sum of set " sets, " is , sum, "."
Set total = total + sum
Set sum = 0
End For
Display "The total of all the sets is total , "."

- (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.arrow_forwardWhat 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_forward
- Please 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_forwardPlease solve and show all steps. True or false? Consider congestion control in TCP. When the timer expires at the sender, the value of ssthresh is set to one-half of the last congestion window.arrow_forwardPlease solve and show all work. What are the purposes of the SNMP GetRequest and SetRequest messages?arrow_forward
- Please solve and show all steps. Three types of switching fabrics are discussed in our course. List and briefly describe each type. Which, if any, can send multiple packets across the fabric in parallel?arrow_forwardPlease solve and show steps. List the four broad classes of services that a transport protocol can provide. For each of the service classes, indicate if either UDP or TCP (or both) provides such a service.arrow_forwardPlease solve and show all work. What is the advantage of web caches, and how does it work?arrow_forward
- Please 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_forwardPlease solve and show all work. Recall that TCP can be enhanced with SSL to provide process-to-process security services, including encryption. Does SSL operate at the transport layer or the application layer?arrow_forwardPlease solve and show all work. Compute the checksum of the words 1011 1001, 1001 1110, and 0111 1011. Show all work.arrow_forward
