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",&qu…
给定由 N 个小写字母字符串组成的数组 A,其中每个字符串长度相等. 选取一个删除索引序列,对于 A 中的每个字符串,删除对应每个索引处的字符. 所余下的字符串行从上往下读形成列. 比如,有 A = ["abcdef", "uvwxyz"],删除索引序列 {0, 2, 3},删除后 A 为["bef", "vyz"], A 的列分别为["b","v"], ["e",&…
