Hey Ashutosh, When we use sort function of stl we can pass a custom compare function which describes how we want to compare the two objects. For reference you can check this code.

bool compare(string a,string b){
	return tolowerCase(a)<tolowerCase(b);
}

This code compares string a and b, return true if string a is lexicographically smaller than string b else it will return false.
