computational complexity when running program like this the times that you get will depend not only on the actual operations being performedbut the times will also depend on what other activity is occurring on the computer where the test is being run all modern operating systemslike mac os xlinuxor microsoft windowsare multi-tasking this means the operating system can switch between tasks so that we can get email while writing computer programfor instance when we time something we will not only see the effects of our own program runningbut all programs that are currently running on the computer it is nearly impossible to completely isolate one program in multi-tasking system howevermost of the time short program will run without too much interruption the program in sect writes an xml file with its results the xml file format supports the description of experimentally collected data for two dimensional plot of one or more sequences of data one sample of the data that this program generates looks like sect the data is abbreviatedbut the format is as shown in sect plot xml sample list size microseconds this copy belongs to 'acha
