LeetCode 944 删列造序[数组] HERODING的LeetCode之路

Posted 2022-05-17 HERODING23

解题思路：
遍历每一列进行判断即可，代码如下：

class Solution 
public:
    int minDeletionSize(vector<string>& strs) 
        int res = 0;
        int row = strs.size(), col = strs[0].size();
        for(int j = 0; j < col; j ++) 
            for(int i = 0; i < row - 1; i ++) 
                if(strs[i][j] > strs[i + 1][j]) 
                    res ++;
                    break;
                
            
        
        return res;
    
;
