A function called max_num() that has three parameters named num1, num2, and num3. The function should return the largest of these three numbers. If any of two numbers tie as the largest, you should return "It's a tie!".

# Write your max_num function here:

def max_num(num1, num2, num3):
  # if (num1>num2) and (num1>num3) return num1
  # if (num1>num2) and (num1>num3) return num1
  list = [num1, num2, num3]
  list.sort()
  # print(list[0])
  # print(list[1])
  # print(list[2])
  first = list[-1]
  second = list[-2]
  
  if first>second: return first
  elif first==second: 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!"
