Pizza cut problem (Or Circle Division by Lines)


Given number of cuts, find the maximum number of possible pieces.


Input  : 2
Output : 4

Input  : 3

This problem is nothing but The Lazy Caterer’s Problem and has below formula.

Maximum number of pieces = 1 + n*(n+1)/2

Refer this for proof.

// C++ program to find maximum no of pieces
// by given number of cuts
using namespace std;

// Function for finding maximum pieces
// with n cuts.
int findMaximumPieces(int n)
   return 1 + n*(n+1)/2;	

// Driver code
int main()
   cout << findMaximumPieces(3);
   return 0;
