input_description: Input is given from Standard Input in the following format:
  
      
      
      N
      a_1 a_2 \cdots a_N
attempt: n, *A = map(int, open(0).read().split())
  print(len([a for i, a in enumerate(A, 1) if i % 2 == a % 2 == 1]))
  
problem_description: Statement
  
  We have N squares assigned the numbers 1,2,3,\ldots,N. Each square has an
  integer written on it, and the integer written on Square i is a_i.
  
  How many squares i satisfy both of the following conditions?
  
    * The assigned number, i, is odd.
    * The written integer is odd.
