问题描述

　　足球赛上，只见Q神如闪电般的速度带球时而左，时而右，时而前，时而后，时而上，时而下……等等，有什么奇怪的东西混进去了？假设Q神力量可以突破地心引力，他在一个三维空间里面可以沿着直角坐标系的坐标轴方向前进。告诉你他的每一次转的方向以及前进的距离，请你回答他最后在哪个位置，面朝那一个方向。假设他一开始在（0，0，0），面朝x轴的正方向。

输入格式

　　多组输入数据。
　　每组第一行是一个整数n。接下来n行每行一个字符表示方向，接着一个整数表示前进距离。其中，f（forward）表示继续前进，方向不变；b（back）表示向后转；l（left）表示向左转；r（right）表示像右转；u（up）表示向上；d（表示向下）。如图示。

输出格式

　　对于每一组数据，输出Q神的坐标和他的朝向。其中：左手系的x正方向、y正方向、z正方向分别位0、1、2，对应的负方向分别为3、4、5.

样例输入

6
l 10
r 11
u 12
d 13
f 14
b 15

样例输出

23 -10 12 3

数据规模和约定

　　数据组数不超过10组，n《＝200 ，每次移动距离不超过100

} 

思路：需要知道Q神的脸的朝向、脚的站位（头指向脚的方向）才能确定Q神的位置。已知脸的朝向，可能有4个站位。

例如：初始位置：脸的朝向为0，脚的站位为5
