#3

Given the following code snippet :

bool comp(string s1, string s2)
{
if(s1.length() < s2.length())
return 1;
else if(s1.length() > s2.length())
return 0;
else return s1 < s2;
}

vector< string > data = {“b”, “a”, “c”, “abc”, “bca”, “xy”};
sort(data.begin(), data.end(), comp);
for(string item : data)
cout << item << " ";

@anujsharmabadboy

here first we are comparing lengths of string i.e string of smaller size will come first and then larger size.

if lenght of both string is same then we are sorting them lexicographically (dictionary order)
now try to predict output
