205. 同构字符串 给定两个字符串 s 和 t,判断它们是否是同构的. 如果 s 中的字符可以被替换得到 t ,那么这两个字符串是同构的. 所有出现的字符都必须用另一个字符替换,同时保留字符的顺序.两个字符不能映射到同一个字符上,但字符可以映射自己本身. 示例 1: 输入: s = "egg", t = "add" 输出: true 示例 2: 输入: s = "foo", t = "bar" 输出: false 示例 3:…
题目: 给定两个字符串 s 和 *t*,判断它们是否是同构的. 如果 s 中的字符可以被替换得到 *t* ,那么这两个字符串是同构的. 所有出现的字符都必须用另一个字符替换,同时保留字符的顺序.两个字符不能映射到同一个字符上,但字符可以映射自己本身. Given two strings s* and t*, determine if they are isomorphic. Two strings are isomorphic if the characters in s* can be rep…
Given two strings s and t, determine if they are isomorphic. Two strings are isomorphic if the characters in s can be replaced to get t. All occurrences of a character must be replaced with another character while preserving the order of characters.…

Question 205. Isomorphic Strings Solution 题目大意:判断两个字符串是否具有相同的结构 思路:构造一个map,存储每个字符的差,遍历字符串,判断两个两个字符串中相同位置字符的差是否相同 Java实现: public boolean isIsomorphic(String s, String t) { Map<String, Integer> map = new HashMap<>(); for (int i=0; i<s.length(…
Isomorphic Strings Given two strings *s* and *t*, determine if they are isomorphic. Two strings are isomorphic if the characters in *s* can be replaced to get *t*. All occurrences of a character must be replaced with another character while preservin…
