两个字符串不同字符相互对应：一个字符只能映射一个字符，不同字符不允许映射到同一字符。
开辟两个265个空间的数组，其中0-127储存常规字符对应ASCII码，128-255储存拓展的ASCII码。
class Solution {
public:
bool isIsomorphic(string s, string t) {
vector<int> cTois(256,0);
vector<int> cToit(256,0);
for (int i = 0; i < s.size(); ++i ) {
if (cTois[s[i]] != cToit[t[i]])
return false;
cTois[s[i]] = i + 1;
cToit[t[i]] = i + 1;
}
return true;
}
};
