output_description: Print the answer in N-K lines.  
  The i-th line should contain `Yes` if the grade for the (K+i)-th term is
  greater than the grade for the (K+i-1)-th term, and `No` otherwise.

problem_description: Statement
  
  M-kun is a student in Aoki High School, where a year is divided into N terms.  
  There is an exam at the end of each term. According to the scores in those
  exams, a student is given a grade for each term, as follows:
  
    * For the first through (K-1)-th terms: not given.
    * For each of the K-th through N-th terms: the multiplication of the scores in the last K exams, including the exam in the graded term.
  
  M-kun scored A_i in the exam at the end of the i-th term.  
  For each i such that K+1 \leq i \leq N, determine whether his grade for the
  i-th term is **strictly** greater than the grade for the (i-1)-th term.
