leetcode-168周赛-1295-统计位数为偶数的数字

class Solution:
    def findNumbers(self, nums: List[int]) -> int:
        ans=0
        for num in nums:
            if len(str(num))%2==0:
                ans+=1
        return ans

class Solution:
    def findNumbers(self, nums: List[int]) -> int:
        return sum(1 for num in nums if int(math.log10(num) + 1) % 2 == 0)
