这是悦乐书的第362次更新,第389篇原创 01 看题和准备 今天介绍的是LeetCode算法题中Easy级别的第224题(顺位题号是944).我们给出了一个N个小写字母串的数组A,它们的长度都相同. 现在,我们可以选择任何一组删除索引,对于每个字符串,我们删除这些索引中的所有字符. 例如,如果我们有一个数组A = ["abcdef","uvwxyz"]和删除索引{0,2,3},那么删除后的数组变成了["bef","vyz"]…

题目如下: We are given an array A of N lowercase letter strings, all of the same length. Now, we may choose any set of deletion indices, and for each string, we delete all the characters in those indices. For example, if we have an array A = ["abcdef&quo…

problem 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) { ; ; i<A[].size(); i++) { ; j<A.size()-; j++) { ][i]) { res++; break; } }…
