# A problem with Group Anagrams

• I am confused that why I ran the algorithm on my eclipse correctly but failed to pass leetcode with the testcase ["tea","","eat","","tea",""]。

public class Solution {
public List<List<String>> groupAnagrams(String[] strs) {
boolean used[]=new boolean[strs.length];
List<List<String>> list=new ArrayList<>();
List<String> tempList=new ArrayList<>();
List<String> nullList=new ArrayList<>();
String temp="";
boolean f=true;
boolean flag=true;

``````    while(flag){
//"eat", "tea", "tan", "ate", "nat", "bat"
for(int i=0;i<strs.length;i++){
f=true;

if(used[i]==false){
if(tempList.isEmpty()){
tempList.add(strs[i]);
temp=strs[i];
used[i]=true;
}
else{
if(strs[i]==""){
used[i]=true;
nullList.add(strs[i]);
f=false;
continue;
}
else{
for(int j=0;j<strs[i].length();j++){

if(temp.indexOf(strs[i].charAt(j))<0){
f=false;
continue;
}
}

}

if(f){
tempList.add(strs[i]);
used[i]=true;
}

}

}
}
list.add(new ArrayList<>(tempList));
tempList.clear();
flag=false;
for(int k=0;k<strs.length;k++)
if(used[k]==false)
flag=true;
}

if(!nullList.isEmpty()){
list.add(new ArrayList<>(nullList));
}

return list;
}
``````
