问题描述
某校的惯例是在每学期的期末考试之后发放奖学金。发放的奖学金共有五种,获取的条件各自不同:
院士奖学金,每人8000元,期末平均成绩高于80分(>80),并且在本学期内发表1篇或1篇以上论文的学生均可获得;
五四奖学金,每人4000元,期末平均成绩高于85分(>85),并且班级评议成绩高于80分(>80)的学生均可获得;
成绩优秀奖,每人2000元,期末平均成绩高于90分(>90)的学生均可获得;
西部奖学金,每人1000元,期末平均成绩高于85分(>85)的西部省份学生均可获得;
班级贡献奖,每人850元,班级评议成绩高于80分(>80)的学生干部均可获得;
只要符合条件就可以得奖,每项奖学金的获奖人数没有限制,每名学生也可以同时获得多项奖学金。例如姚林的期末平均成绩是87分,班级评议成绩82分,同时他还是一位学生干部,那么他可以同时获得五四奖学金和班级贡献奖,奖金总数是4850元。
基本要求
现在给出若干学生的相关数据,请计算哪些同学获得的奖金总数最高(假设总有同学能满足获得奖学金的条件)。
输入数据格式格式:
输入的第一行是一个整数N(1 <= N <= 100),表示学生的总数。接下来的N行每行是一位学生的数据,从左向右依次是姓名,期末平均成绩,班级评议成绩,是否是学生干部,是否是西部省份学生,以及发表的论文数。姓名是由大小写英文字母组成的长度不超过20的字符串(不含空格);期末平均成绩和班级评议成绩都是0到100之间的整数(包括0和100);是否是学生干部和是否是西部省份学生分别用一个字符表示,Y表示是,N表示不是;发表的论文数是0到10的整数(包括0和10)。每两个相邻数据项之间用一个空格分隔。
输出数据格式:
输出包括三行,第一行是获得最多奖金的学生的姓名,第二行是这名学生获得的奖金总数。如果有两位或两位以上的学生获得的奖金最多,输出他们之中在输入文件中出现最早的学生的姓名。第三行是这N个学生获得的奖学金的总数。
输入

YaoLin 87 82 Y N 0
ChenRuiyi 88 78 N Y 1
LiXin 92 88 N N 0
ZhangQin 83 87 Y N 1
输出
ChenRuiyi
