2481. Minimum Cuts to Divide a Circle

A valid cut in a circle can be:

• A cut that is represented by a straight line that touches two points on the edge of the circle and passes through its center, or
• A cut that is represented by a straight line that touches one point on the edge of the circle and its center.

Some valid and invalid cuts are shown in the figures below.

class Solution {
public:
    int numberOfCuts(int n) {
        if(n == 1) return 0;
        if(n % 2 == 0) return n / 2;
        return n;
    }
};
