Hi Sherif



Samer has sent me a copy of your puzzle in PDF.



I have no intention of doing your coursework for you but the method of solution is very simple and should take you about 30 minutes.



Set the tasks A B C D etc into a gantt chart using the durations and links as stated.



Set them all to ASAP and reschedule - note the dates.



Fix the chart as a baseline and set the tasks to ALAP and reschedule - note the dates.



You now compare the early dates with the later dates. (NET - NLT - which Samer tells me means Not Earlier Than and Not Later Than)



To my mind the whole excercise is completely pointless and is teaching you bad programming habits.



Best regards

Hello Mike,



Indeed. Seems that our new friend has something to share, but doesn’t know the write place to post it.



Have a great evening,



Samer
