// Name: Pi calculator / bench mark
// Description:My code benchmarks the CP
//     U buy calculating Pi (3.1415....) with b
//     rute force
// By: Vadim Oguievetski
//
// Inputs:#no inputs#
//
// Returns:returns the value of Pi and t
//     he time taken
//
// Assumes:try to tweek the 'r' value
//
// Side Effects:My program might make yo
//     u want to have a pie which can cause obe
//     sity.
