Sally the Programmer thinks her programming job is finished. She offers you her code, believing it is working perfectly. You use it but report that your driver code which calls her code doesn’t seem to be working correctly. Why? What needs to be done to Sally’s code to make it work properly?

Use a physical stopwatch to record the length of time it takes to run the program. calculate the difference obtained by calls to the method system.currenttimemillis() 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() at the start of the program and at the end of the program so that the elapsed time includes the display of the result. use the value returned by the method system.currenttimemillis() just after the end of the algorithm as the elapsed time.
