165. Compare Version Numbers
题目:
https://leetcode.com/problems/compare-version-numbers/
难度:
Easy
其实我并不觉得这个很简单
因为可能两个的位数不一样，首端或者尾端需要补0，同时我还考虑过可能有出现多个'.'的状况
class Solution(object):
def compareVersion(self, version1, version2):
"""
:type version1: str
:type version2: str
:rtype: int
"""
v1 = version1.split('.')
v2 = version2.split('.')
v1 = [int(x) for x in v1]
v2 = [int(x) for x in v2]
len1 = len(v1)
len2 = len(v2)
lenMax = max(len1, len2)
for x in range(lenMax):
v1Token = 0
if x < len1:
v1Token = v1[x]
v2Token = 0
if x < len2:
v2Token = v2[x]
if v1Token > v2Token:
return 1
elif v1Token < v2Token:
return -1
return 0
