205-Isomorphic Strings
code
class Solution {
public:
bool isIsomorphic(string s, string t) {
if(s.size()!=t.size()) return false;
int len = s.size();
char hash_s[128] = {0}, hash_t[128] = {0};
for(int i=0; i<len; i++)
{
if(hash_s[s[i]] != hash_t[t[i]]) return false;
hash_s[s[i]] = i+1;//
hash_t[t[i]] = i+1;//
}
return true;
}
};
需要注意的
1;//
hash_t[t[i]] = i+1;//
