c. It would still be correct, but run a little faster d. There would be no effect. 13. Which process is recommended for calculating the elapsed running time of an algorithm? a. Use a physical stopwatch to record the length of time it takes to run the program. b. Calculate the difference obtained by calls to the method System.currentTimeMillis b. Calculate the difference obtained by calls to the method System.currentTimeMi11is just before the start of the algorithm and just after the end of the algorithm. Calculate the difference obtained by calls to the method System. currentTimeMillis () the start of the program and at the end of the program so that the elapsed time includes the display of the result. d. Use the value returned by the method System.currentTimeMillis just after the en the algorithm as the elapsed time
