网址：https://leetcode.com/problems/binary-prefix-divisible-by-5/

一次for循环遍历数组，在上次计算的基础上得到本次的结果！

 class Solution {
 public:
     vector<bool> prefixesDivBy5(vector<int>& A)
     {
         vector<bool> ans;
         int num = ;
         int pre_num = ;
         for(int i=; i<A.size(); i++)
         {
             num = ;
             num += pre_num *  + A[i];
             num = num % ;
             pre_num = num;
             if(num %  == )
             {
                 ans.push_back(true);
             }
             else
                 ans.push_back(false);
         }
         return ans;
     }
 };
