Answer:
O(n²)
Explanation:
The worse case time complexity of insertion sort using binary search for positioning of data would be O(n²).
This is due to the fact that there are quite a number of series of swapping operations that are needed to handle each insertion.
There are pros and cons to using special characters in email subject lines. Generally, marketers report higher open rates.

Concatenation allows you to add multiple strings together to form one long string by using the '+' operator between each string, so the purpose of concatenation is "<em>to combine two or more strings into one big string</em>" (third option).
Hope this helps :)
Answer
Procedural programming, Object-oriented programming
Explanation
Procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures within its development period of time. It contains a systematic order of statements, functions and commands to complete a computational task or program. It is centered on creating procedures. While object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. It has four principles which are inheritance, polymorphism, abstraction and Encapsulation
Answer:
In C++:
#include <iostream>
using namespace std;
int main(){
string fname,lname; int num;
cout<<"Firstname: "; cin>>fname;
cout<<"Lastname: "; cin>>lname;
cout<<"4 digits: "; cin>>num;
string login = lname;
if(lname.length()>=5){
login = lname.substr(0, 5); }
login+=fname.substr(0,1)+to_string(num%100);
cout<<login;
return 0;
}
