PROBLEM ONE: MARS ROVERS

A squad of robotic rovers are to be landed by NASA on a plateau on Mars.

This plateau, which is curiously rectangular, must be navigated by the

rovers so that their on-board cameras can get a complete view of the

surrounding terrain to send back to Earth.

A rover's position and location is represented by a combination of x and y

co-ordinates and a letter representing one of the four cardinal compass

points. The plateau is divided up into a grid to simplify navigation. An

example position might be 0, 0, N, which means the rover is in the bottom

left corner and facing North.

In order to control a rover, NASA sends a simple

string of letters. The

possible letters are 'L', 'R' and 'M'. 'L' and 'R' makes the rover spin 90

degrees left or right respectively, without moving from its current spot.

'M' means move forward one grid point, and maintain the same heading.

Assume that the square directly North from (x, y) is (x, y+1).

INPUT:

The first line of input is the upper-right coordinates of the plateau, the

lower-left coordinates are assumed to be 0,0.

The rest of the input is information pertaining to the rovers that have

been deployed. Each rover has two lines of input. The first line gives the

rover's position, and the second line is a series of instructions telling

the rover how to explore the plateau.

The position is made up of two integers and a letter separated by spaces,

corresponding to the x and y co-ordinates and the rover's orientation.

Each rover will be finished sequentially, which means that the second rover

won't start to move until the first one has finished moving.

OUTPUT

The output for each rover should be its final co-ordinates and heading.

PROBLEM TWO: SALES TAXES

Basic sales tax is applicable at a rate of 10% on all goods, except books,

food, and medical products that are exempt. Import duty is an additional

sales tax applicable on all imported goods at a rate of 5%, with no

exemptions.

When I purchase items I receive a receipt which lists the name of all the

items and their price (including tax), finishing with the total cost of the

items, and the total amounts of sales taxes paid. The rounding rules for

sales tax are that for a tax rate of n%, a shelf price of p contains

(np/100 rounded up to the nearest 0.05) amount of sales tax.

Write an application that prints out the receipt details for these shopping

baskets...
