 5. Define two work items with their functions. One for the code from the timer function, and the second for the code from the main function. Instead of executing the full code in the timer and main function submit corresponding work items. The code for the timer work item can look as follows (the code for the main function as well as the work items definition and initialization write on your own). Experiment with the maximal iteration value in the "for" loop. Describe observation results in the report. 5. Define two work items with their functions.
