从patient_id中找到最常用的数字,可以通过以下步骤进行:
- 遍历所有的patient_id,将其拆分为单个数字或字符。
- 统计每个数字或字符出现的次数,可以使用字典或哈希表数据结构来记录。
- 找到出现次数最多的数字或字符。
- 返回出现次数最多的数字或字符作为最常用的数字。
举例说明:
假设有一组patient_id如下所示:
patient_id = ["P123", "P456", "P789", "P456", "P123", "P123", "P789", "P789"]
按照上述步骤进行操作:
- 将每个patient_id拆分为单个字符,得到["P", "1", "2", "3", "P", "4", "5", "6", "P", "7", "8", "9", "P", "4", "5", "6", "P", "1", "2", "3", "P", "1", "2", "3", "P", "7", "8", "9", "P", "7", "8", "9"]。
- 统计每个字符出现的次数,得到{"P": 8, "1": 4, "2": 4, "3": 4, "4": 2, "5": 2, "6": 2, "7": 4, "8": 4, "9": 4}。
- 找到出现次数最多的字符是"P",出现了8次。
- 返回结果:"P"是最常用的数字。
