AT_abc397_a [ABC397A] Thermometer

Takahashi measured his body temperature and found it to be $ X $ $ {}^\circ $ C. Body temperature is classified into the following: - Higher than or equal to $ 38.0 $ $ {}^\circ $ C: “High fever” - Higher than or equal to $ 37.5 $ $ {}^\circ $ C and lower than $ 38.0 $ $ {}^\circ $ C: “Fever” - Lower than $ 37.5 $ $ {}^\circ $ C: “Normal” Which classification does Takahashi's body temperature fall into? Present the answer as an integer according to the Output section.

The input is given from Standard Input in the following format: > $ X $

Print an integer specified below corresponding to Takahashi's body temperature classification. - High fever: $ 1 $ - Fever: $ 2 $ - Normal: $ 3 $

### Sample Explanation 1 His body temperature is $ 40.0 $ $ {}^\circ $ C, which is classified as a high fever. Thus, print $ 1 $ . ### Sample Explanation 2 His body temperature is $ 37.7 $ $ {}^\circ $ C, which is classified as a fever. Thus, print $ 2 $ . ### Sample Explanation 3 His body temperature is $ 36.6 $ $ {}^\circ $ C, which is classified as a normal temperature. Thus, print $ 3 $ . ### Constraints - $ 30 \leq X \leq 50 $ - $ X $ is given to one decimal place.
