How would you design the data structures for a very large social network like Facebook or Linkedln? Describe how you would design an algorithm to show the shortest path between two people (e.g., Me-> Bob-> Susan-> Jason-> You).

Describe the variations among Java's TreeMap, HashMap, and LinkedHashMap. Give an instance of when each might be most effective.

Implement a simple heuristic for TSP with web interface and display (web). Should use classes and objects.

Java programming.

Implement an NxN jigsaw puzzle. Design the data structures and explain an algorithm to solve the puzzle. You can assume that you have a fi tsWi th method which, when passed two puzzle edges, returns true if the two edges belong together

The language is Java. Given my code, I want to make my output look like the first part of the first image's output, but with the numbers in my output. The other two pictures are of my code. I want to make the output look like a tree, as opposed to being close together like that. Thanks.

It is unclear how many nodes are included in the strongest linkedlist currently available.Is there one in particular that sticks out as being very protracted?
