Code Must be in Python. I will upvote you. 

Convert the following recursive functions into iterative ones:
1.
def sum_odd (n, total):
if n == 1: return total
elif n % 2 == 0: return sum_odd (n - 1, total)
else return sum_odd (n - 2, total + n)
2.
3.
def max (I, n):
if I ==
[]: return n
elif [0] >n : return max (1[1:], 1[0])
else return max (1[1:], n)
def mylen (1, n):
if I == =: return n
else : return mylen (1[1:], n +1)
