Consider the Dead Sea Scrolls. Imagine that you have these torn up old shreds of paper with ancient
words on them. You want to develop an application that will display one sheet at a time on the screen. When the user left-clicks a word, the page containing the previous occurence of that word is displayed and the word is highlighted. When the user right-clicks a word, the page containing the next occurence is displayed and the word is highlighted. When the user double-clicks a word, the definition is displayed. How would you design the application?

Given an array of the counties in NY represented as arrays of line segments, find the collection of line segments which represent the outline of the state.

Imagine a trainyard. The purpose of a trainyard is to reorder trains so that they are most efficiently grouped for outbound travel. The basic unit of a trainyard is a piece of track which looks like the figure below. The train operator can perform three operations: move a car from the source to the spur, from the source to the destination, or from the spur to the destination. So, for example, he could reverse a train by moving each car onto the spur and then moving each car onto the destination. Write a function which, given an array of integers representing the order of cars on the source, and another
representing the order of cars desired on the destination, prints instructions telling the trainyard operator which operations to perform to reorder the train correctly.

Implement a function which, given the integer value of the hours and minutes hands of a clock, returns the measure of the degrees between them.
