Difficulty—

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 $90$. Takahashi took this test and got $X$ points. Find the minimum number of extra points needed to go up one rank higher. If, however, his rank was Expert, print `expert`, as there is no higher rank than that. ## Constraints * $0 \leq X \leq 100$ * $X$ is an integer. ## Input Input is given from Standard Input in the following format: $X$ [samples]
