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.…

public class Solution { public bool IsIsomorphic(string s, string t) { if (s.Length != t.Length) { return false; } else { Dictionary<char, int> dic1 = new Dictionary<char, int>(); Dictionary<char, int> dic2 = new Dictionary<char, int&…

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: 输入: s = &q…
