output_description: Print the number of divisors in a line.
input_description: Three integers a, b and c are given in a line separated by a single space.
attempt: a = list(map(int, input().split()))
  b = a[0]
  c = a[1]
  d = a[2]
  e = []
  for i in range(b, c + 1):
      if d % i == 0:
          e.append(i)
  print(len(e))
  
problem_description: How Many Divisors?
