Software packages A and B of complexity O(nlogn) and O(n), respectively, spend exactly TA(n)=cAnlog2n and TB(n)=cBn milliseconds to process n data items. During a test, the average time of processing n=1024 data records with the packages A and B is 2048 milliseconds and 3072 milliseconds, respectively. Work out exact conditions when one package outperforms the other and recommend the best choice if up to n=5120 items should be processed
