Coding Dojo por Agile-Barcelona & Runroom
Friday 19 April 2013, 19:00 - 21:00
Milà i Fontanals, 14, Barcelona, España
El próximo viernes, 19 de Abril, a las 19 horas, vamos a realizar en Runroom una nueva edición coding dojo de barcelona, con el ya habitual e inestimable patrocinio de Úbeda Gin&Tapas que nos suministra los GinTonics.
¿En qué consiste un Coding Dojo?
Un Coding Dojo es un encuentro que celebra un grupo de desarrolladores para trabajar en un reto de programación.
Hay varias maneras de celebrar un Coding Dojo. Nosotros solemos optar por el formato PreparedKata: nos organizarnos en parejas para practicar pair programming y tratamos de resolver la kata acordada en un tiempo limitado, usando TDD y BabySteps.
Kata elegida
Apoyamos la iniciativa 12 meses 12 katas y trataremos de resolver la kata propuesta en su página para este mes.
TODOS LOS NIVELES!
Que no te intimide todo esto del TDD y el eXtreme Programming eh? Todos venimos a aprender, practicar y sobre todo, a pasarlo bien. Lo importante es aprovechar el espacio para equivocarse sin temor. :-)
En esta ocasión realizaremos una kata un tanto diferente, a continuación podéis encontrar el enunciado.
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.
INPUT AND OUTPUT
Test Input: 5 5 1 2 N LMLMLMLMM 3 3 E MMRMMRMRRM
Expected Output: 1 3 N 5 1 E
