# Write your max_num function here:

def max_num(num1, num2, num3):
  if num1 > num2 and num1 > num3:
    return num1
  elif num2 > num1 and num2 > num3:
    return num2
  elif num3 > num1 and num3 > num2:
    return num3
  elif num2 > num3 and num1 == num2:
    return "It's a tie!"
  elif num3 > num2 and num3 == num1:
    return "It's a tie!"
  elif num3 > num1 and num2 == num3:
    return "It's a tie!"

# Uncomment these function calls to test your max_num function:
print(max_num(-10, 0, 10))
# should print 10
print(max_num(-10, 5, -30))
# should print 5
print(max_num(-5, -10, -10))
# should print -5
print(max_num(2, 3, 3))
# should print "It's a tie!"
