102190: [AtCoder]ABC219 A - AtCoder Quiz 2
Description
Score : $100$ points
Problem Statement
In the Kingdom of AtCoder, there is a standardized test of competitive programming proficiency.
An examinee will get a score out of $100$ and obtain a rank according to the score, as follows:
- Novice, for a score not less than $0$ but less than $40$;
- Intermediate, for a score not less than $40$ but less than $70$;
- Advanced, for a score not less than $70$ but less than $90$;
- Expert, for a score not less than $90$.

问题描述
在AtCoder王国，有一个标准化的编程竞技能力测试。
应试者将得到一个$100$分之内的分数，并根据分数获得一个排名，如下所示：
- 新手，分数不小于$0$但小于$40$；
- 中级，分数不小于$40$但小于$70$；
- 高级，分数不小于$70$但小于$90$；
- 专家，分数不小于$90$。
