problem_description: Statement
  
  In the Kingdom of AtCoder, people use a language called Taknese, which uses
  lowercase English letters.
  
  In Taknese, the plural form of a noun is spelled based on the following rules:
  
    * If a noun's singular form does not end with `s`, append `s` to the end of the singular form.
    * If a noun's singular form ends with `s`, append `es` to the end of the singular form.
  
  You are given the singular form S of a Taknese noun. Output its plural form.
