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
