leetcode 165 Compare Version Numbers python

纯属吐槽。。那坑爹的题目，不过也有可能是我e文没看太仔细吧

原题目

Compare two version numbers version1 and version2.
If version1 > version2 return 1, if version1 < version2 return -1, otherwise return 0.

You may assume that the version strings are non-empty and contain only digits and the . character.
The . character does not represent a decimal point and is used to separate number sequences.
For instance, 2.5 is not "two and a half" or "half way to version three", it is the fifth second-level revision of the second first-level revision.

Here is an example of version numbers ordering:

0.1 < 1.1 < 1.2 < 13.37

目测就是一个版本号比较，搞起。。。

然后就掉坑里了。。

看测试用例，尼玛。。 拿‘0‘ 跟‘1‘比较。。。 你赢了。。

继续。。 尼玛 testcase 里面有‘0.0.1‘

算你狠。。。 接着改

最后一个是‘0.1‘跟‘0.0.1‘ 比较版本...

你大爷。。。

最终版本。。虽然确实丑了点

最终版本

        deep = max(len(v1), len(v2), 2)

        while len(v1) < deep:
            v1.append(0)

        while len(v2) < deep:

                return -1
        return 0

        for str in substrings:
            v.append(int(str))
        return v

    def __init__(self):
        ans = self.compareVersion(‘0.1‘, ‘0.0.1‘)
        print(ans)

solution = Solution()

最后pycharm大法好。。。
