Maximum points of intersection n circles in C++

In this tutorial, we will be discussing a program to find maximum points of intersection n circles

For this we will be provided with the number of circles. Our task is to find the maximum number of intersections the given number of circles meet.

Example

#include <bits/stdc++.h>
using namespace std;
//returning maximum intersections
int intersection(int n) {
   return n * (n - 1);
}
int main() {
   cout << intersection(3) << endl;
   return 0;
}

Output
