input: Write a function to find the maximum of three numbers. Define a function named "max_of_three" that takes three parameters a, b, and c as inputs, and returns the largest of these three numbers. If the inputs are 3, 4, and 5, the output should be 5.
  
  def max_of_three(a, b, c):
      if a > b and a > c:
          return a
      elif b > a and b > c:
          return b
      else:
          return c
  
  assert max_of_three(3, 4, 5)==5
  assert max_of_three(5, 4, 3)==5
  assert max_of_three(4, 3, 5)==5
  assert max_of_three(10, 2, 8)==10
output: def max_of_three(a, b, c):
      if a > b and a > c:
          return a
      elif b > a and b > c:
          return b
      else:
          return c
