Given two strings s1, s2, find the lowest ASCII sum of deleted characters to make two strings equal. Example 1: Input: s1 = "sea", s2 = "eat" Output: 231 Explanation: Deleting "s" from "sea" adds the ASCII value of…

Freedom of Choice URAL - 1517 Background Before Albanian people could bear with the freedom of speech (this story is fully described in the problem "Freedom of speech"), another freedom - the freedom of choice - came down on them. In the near fu…
Given a string s1, we may represent it as a binary tree by partitioning it to two non-empty substrings recursively. Below is one possible representation of s1 = "great": great / \ gr eat / \ / \ g r e at / \ a t To scramble the string, we may ch…

给定两个字符串 s 和 t,它们只包含小写字母.字符串 t 由字符串 s 随机重排,然后在随机位置添加一个字母.请找出在 t 中被添加的字母. 示例: 输入: s = "abcd" t = "abcde" 输出: e 解题思路:该题的解法和上一篇我们解决问题的思路一样,同样此题我们需要定义两个数组arr1和arr2分别存储字符串s和t每一个字符出现的次数,遍历统计字符串每一个字符出现的次数,最后遍历,找出arr1和arr2不相等,不相等的坐标存储的就是字符串t中添加…

今天碰到一个算法题觉得比较有意思,研究后自己实现了出来,代码比较简单,如发现什么问题请指正.思路和代码如下: 基本思路:从左开始取str的最大子字符串,判断子字符串是否为str的后缀,如果是则返回str加子字符串剩余部分:如果不是则逐步减少子字符串长度后在进行比较./* * 给出一个字符串s,输出包含两个字符串s的最短字符串,如s为abca时,输出则为abcabca */ public class ContainTwoString { public static String MergeStri…
