找出字符串的可整除数组

class Solution {
public:
    vector<int> divisibilityArray(string word, int m) {
        vector<int> ans;
        long long div = 0;
        for (auto w : word) {
            div = (div * 10 + w - '0') % m;
            if (div) ans.push_back(0);
            else ans.push_back(1);
        }
        return ans;
    }
};
