PTA 5-13 日K蜡烛图 (15分)

股票价格涨跌趋势，常用蜡烛图技术中的K线图来表示，分为按日的日K线、按周的周K线、按月的月K线等。以日K线为例，每天股票价格从开盘到收盘走完一天，对应一根蜡烛小图，要表示四个价格：开盘价格Open（早上刚刚开始开盘买卖成交的第1笔价格）、收盘价格Close（下午收盘时最后一笔成交的价格）、中间的最高价High和最低价Low。

如果Close<<Open，表示为“BW-Solid”（即“实心蓝白蜡烛”）；如果Close>>Open，表示为“R-Hollow”（即“空心红蜡烛”）；如果Open等于Close，则为“R-Cross”（即“十字红蜡烛”）。如果Low比Open和Close低，称为“Lower Shadow”（即“有下影线”），如果High比Open和Close高，称为“Upper Shadow”（即“有上影线”）。请编程序，根据给定的四个价格组合，判断当日的蜡烛是一根什么样的蜡烛。

输入格式：

输入在一行中给出4个正实数，分别对应Open、High、Low、Close，其间以空格分隔。

输出格式：

在一行中输出日K蜡烛的类型。如果有上、下影线，则在类型后加上with 影线类型。如果两种影线都有，则输出with Lower Shadow and Upper Shadow。

输入样例1：

5.110 5.250 5.100 5.105

输出样例1：

BW-Solid with Lower Shadow and Upper Shadow

输入样例2：

5.110 5.110 5.110 5.110

输入样例3：

5.110 5.125 5.112 5.126

输出样例3：

R-Hollow
