944. Delete Columns to Make Sorted

题意：其实题意很简单，但是题目的description给整糊涂啦。。。直接看题目标题即可理解。

solution:

class Solution {
public:
    int minDeletionSize(vector<string>& A) {
        int res = ;
        for(int i=; i<A[].size(); i++)
        {
            for(int j=; j<A.size()-; j++)
            {
                if(A[j][i]>A[j+][i])
                {
                    res++;
                    break;
                }
            }
        }
        return res;
    }
};
