We can check whether characters are same while sorting. if same character, break the loop ...if it is sorted it means there are no same characters

[lokeshsenthilkumar]

```
bool isIsogram(string s)
{
unordered_set<char> count;
for(char c:s){
if (count.find(c) == count.end())
count.insert(c);
else
return false;
}
return true;
}
```
