Standardize Medicine Name

The problem requires you to standardize the format of a medicine name. Doctors sometimes write medicine names in a messy manner regarding letter casing. You need to convert the medicine name so that if the first character is an alphabet, it is converted to uppercase, and all the remaining letters are converted to lowercase.

For example, both ASPIRIN and aspirin should be converted to Aspirin.

inputFormat

The input consists of a single line containing a non-empty string representing a medicine name. The string may include letters and other characters. If the first character is a letter, apply the formatting as described.
