In this project, you will implement a B+-tree in which each node contain entries of the form?[key, ptr]?and some required header information. In the leaf node,?ptr?is the pointer pointing to the record id of a data record with search key value, and in the non-leaf node(index node),?ptr?is the pointer pointing to the child node which may be index or leaf node. Since we are not implementing data file layer in this project, we will keep all leaf node pointers?NULL<标题>. You must implement the full search and insert algorithms as discussed in class. In particular, your insert routine must be capable of dealing with overflows (at any level of the tree) by splitting pages. Keys should be stored in sorted order. Deletes will be handled by simply deleting the key and pushing the remaining keys in the node. You do not need to implement merging of nodes on deletes. But, you do need to keep all nodes updated without any holes when records are deleted(i.e, when you delete a key

Write a program FlightTest.java that controls two airplanes, one plane1
a commercial plane from Eagle company and one plane2, a ghter-bomber
from Dragon company. All airplanes y at some altitude and with some
speed. They take o and land. Just as bombers may drop bomb (if they
have any) while they are in sky, commercials can board passengers (as much
as their capacity allows) while grounded.
Assuming all planes made by Eagle have 300 seats, y at 39000 ft and 550
mph and all planes made by Dragon have 2 bomb bays and y at 30000 ft
and 1000 mph, develop classes Aircraft, Bomber, Commercial, Eagle and
Dragon and use them in a program FlightTest.java.
Your manager has just learned basic concepts of interfaces and abstraction in
Java and has asked you to implement the methods in the following interface
<标题>Computer games are nearly as old as electronic computers themselves. The first tic-tac-toe game was programmed on an EDSAC vacuum-tube computer. Your job will be to expand the Battleship program started in earlier labs into a fully-playable game.
4.2 The game of Battleship
<标题>Wikipedia has a thorough description of the origins of the game of?. For purposes of this assignment, follow the following rules.
1.The game is played between two players (one human and one computer for your program).
2.Each player has an identical set of ships. Each ship has a length, a name (e.g., “submarine”), and a symbol (a letter, e.g., “S”).
3.Each player has a grid, called the “battle board”,? which is mostly hidden from the other player. The grid is used for marking the locations of the pl
In this project you will be using the knowledge you gained from lectures and homeworks and applying them to a lengthier programming assignment. The answers to some of your questions do not strictly reside in this document. You are encouraged to look at other sources for inspiration. This semester’s project will involve Creating a 2D game. This is an?individual?project, and as such you will be held to the University’s academic integrity policies. You are welcome to discuss strategies and ideas with other students (and will be encouraged to in recitation), but you must code the project on your own.
This project is what you make of it. Listed below are point guidelines as to how they relate to the number of points given to the project (total 100). However, you should not be limited by what we suggest the minimum work required here is. To get the most out of this project, I urge you all to push yourselves to find your limits. You might surprise yourself! Good luck!
<标题>Over the past few years, the concept of a “cloud” where our programs and data can live has become very popular. What makes the cloud possible is a combination of Internet communication (enabling communication with servers located anywhere in the world) and virtualization of resources (enabling providers to offer/sell storage and computation inside the network). We are seeing companies race to put there services in the cloud, and users are rapidly embracing services in the cloud.
One of the most popular services is cloud file storage<标题>; the ability to upload your data to the cloud and then to download it whenever your need it to any device that needs it. Today we see an seemingly endless list of cloud storage providers (e.g., Amazon Cloud Drive, Google Drive, Apple ICloud, Box, DropBox, MS SkyDrive, SpiderOak, and others).
In this project, you will write your own cloud file storage service called mycloud<
