Company Name : Symphony
Type : Experienced
Question Paper Write-up. : Everyone was got the same assignment ie ( java, C#, C, C++) They told everyone to do 1 assignment from 2 in there technologies.... Here are the assignments

Mars Rover

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.

INPUT AND OUTPUT:

Test Input:

5 5
1 2 N
LMLMLMLMM
3 3 E
MMRMMRMRRM

Expected Output:
1 3 N
5 1 E

Game of Life:

The universe of Game of life is an infinite 2-D orthogonal grid of square cells, each of which is in one of two possible states, live or dead. Every cell interacts with its eight neighbours, with its 8 neighbours, which are the cells that are horizontally, veritcally, or diagonally adjacent. At each step in time, the following transitions occur:

Any live cell with fewer than two live neighbours dies, as if caused by under-population.
Any live cell with 2 or 3 live neighbours lives on to the next generation.
Any live cell with more than 3 live neighbours dies, as if by overcrowding.
Any dead cell with exactly 3 live neighbours becomes a live cell, as if be reproduction.

The initial pattern constitutes the seed of the system. The 1st generation is created by applying the above rules simultaneously to every cell in the seed-births and deaths occur simultaneously, and the discrete moment at which this happens is sometimes called a tick( in other words, each generation is a pure function of the preceding one). The rules continue to be applied repeatedly to create further generations.
