If start with 0 jump one step else 1 jump two steps until the loop finishes

```
class Solution(object):
def isOneBitCharacter(self, bits):
"""
:type bits: List[int]
:rtype: bool
"""
flag = None
i = 0
while i < len(bits):
if bits[i] == 0:
flag = True
i += 1
else:
if i < len(bits):
flag = False
i += 2
return flag
