康博嘉 编程题

题目

1.有一组医院科室物品用量数据（代码中getItemList()方法返回的结果），每条数据为某个科室的某种物品用量。
2．要求对这组数据进行数据转换和计算处理，转换成科室物品用量列表（格式如下表），每条记录里面有4种物品用量和总用量，并在此基础上计算全院的平均用量。
3. 要求表格按总用量从高到低排序，最后用控制台输出即可。
科室	A物品	B物品	C物品	D物品	总用量
全科	 89  	78  	88  	87  	342
儿科	 87  	89  	66  	95  	337
…					
平均用量	79  	72  	69  	77  	299
需要注意的是，最终完成代码的代码质量（逻辑是否清晰，变量/方法命名是否合理等），将作为考察标准的一部分
