problem_description: Statement
  
  Takahashi has decided to work on K days of his choice from the N days starting
  with tomorrow.
  
  You are given an integer C and a string S. Takahashi will choose his workdays
  as follows:
  
    * After working for a day, he will refrain from working on the subsequent C days.
    * If the i-th character of S is `x`, he will not work on Day i, where Day 1 is tomorrow, Day 2 is the day after tomorrow, and so on.
  
  Find all days on which Takahashi is bound to work.
