Not sure if this is what you're looking for but it sounds like you
need some kind of zip :
zip [0..] [Just (T4 3 1 3 1), Just (T2 5 1), Nothing]
=> [(0,Just (T4 3 1 3 1)),(1,Just (T2 5 1)),(2,Nothing)]

Hi Hope that You are doing fine. I am stuck at this problem if you have any idea kindly help me out. I want to output the schedule for a given task and method for one hyper period....like (o, just (T4 3 1 3 1), (1, Just (T2 5 1 51) etc
Regards Nowshad data Task = T4 Phase Period Execution Deadline | T2 Period Execution deriving (Show ,Eq) type Phase = TimeUnit type Period = TimeUnit type Execution = TimeUnit type Deadline = TimeUnit type TimeUnit = Int data Method = RM | DM | EDF deriving (Show , Eq) periodicSchedule :: Method -> [Task] -> [(TimeUnit, Maybe Task)]
