现在想对该多维数组进行处理，规则为：当a键的recom_account的值等于b键的trade_account时，则a键值对为b键值对的直接子分类，当c键的recom_account等于a键的trade_account时，则c键值对为b键值对的间接子分类，每个键值对(分类)可以有多个直接子分类，但只对应一个直接父分类，也就是trade_account是唯一的，recom_account不是唯一的。期望返回的结果是：每个键值对增加一个count键，其值为所有直接子分类的个数，一个childlist键，其值为一个多维数组，记录子分类的所有信息，一个total_count键，其值为所有子分类的个数。haschild字段为1表示该分类有子分类(包括直接子分类与间接子分类),为0则没有子分类。如上面的数组，期望生成如下的格式。
