leetcode172. 阶乘后的零(java & python3)

数学题emmm 😅

java:

class Solution {
    public int trailingZeroes(int n) {
        int count = 0;
        while(n > 0){
            count += n / 5;
            n /= 5;
        }
        return count;
    }
}

python3:

class Solution:
    def trailingZeroes(self, n: int) -> int:
        ans = 0
        while n > 0:
            ans += n // 5
            n //= 5
        return ans
