Python using direct access table

  • 0

    I learn how to use direct access table from "Code Complete"

    class Solution(object):
        def compareVersion(self, version1, version2):
            Using direct acess table method instead of complex logic
            :type version1: str
            :type version2: str
            :rtype: int
            v1_lst = version1.split('.')
            v2_lst = version2.split('.')
            table = [-1, 1]
            while v1_lst and v2_lst:
                v1_value, v2_value = int(v1_lst[0]), int(v2_lst[0])
                if v1_value != v2_value:
                    return table[v1_value > v2_value]
                v1_lst = v1_lst[1:]
                v2_lst = v2_lst[1:]
            if not v1_lst and not v2_lst:
                return 0
            elif sum(map(int, v1_lst+v2_lst)) == 0:
                return 0
                return table[not v2_lst]
