Given an array of strings, group anagrams together.
Example:
Input: ["eat", "tea", "tan", "ate", "nat", "bat"],
Output:
[
["ate","eat","tea"],
["nat","tan"],
["bat"]
]
Note:
AC code:
class Solution {
public:
vector<vector<string>> groupAnagrams(vector<string>& strs) {
unordered_map<string, vector<string>> mp;
vector<vector<string>> res;
for (auto str : strs) {
string tage = str;
sort(tage.begin(), tage.end());
mp[tage].push_back(str);
}
for (auto m : mp) {
sort(m.second.begin(), m.second.end());
res.push_back(m.second);
}
return res;
}
};
