In this lab you will write $3$ C$++$ programs, that we will tailor for specific run times,

$1)30$ seconds runtime

$2)75$ second runtime

$3)120$ second runtime

Using the "time" command you will evaluate the difference between running these in the forground and the background, answering the questions int the lab.

You can use the below sample code as a template, this one is for running at roughly $30$ seconds, for the remaining $2$ times, copy this code and increase the n value to increase the computational time.$($this might take some trial and error$)$
