Isomorphic Strings

來源：程序員人生發(fā)布時(shí)間：2015-06-16 08:26:09 閱讀次數(shù)：2917次

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. No two characters may map to the same character but a character may map to itself.

For example,
Given "egg", "add", return true.

Given "foo", "bar", return false.

Given "paper", "title", return true.

Note:
You may assume both s and t have the same length.

class Solution { public: bool isIsomorphic(string s, string t) { int len1=s.length(); map<char,char> m; map<char,char> m2; for(int i=0;i<len1;i++){ if(m.find(s[i])==m.end()&&m2.find(t[i])==m2.end()){ m[s[i]]=t[i]; m2[t[i]]=s[i]; }else if(m[s[i]]!=t[i]||m2[t[i]]!=s[i]){ return false; } } return true; } };
