Encounter a problem, seek a solution

cheeselee

Encountered a problem, seeking a solution:
There are 4 pumps in a pumping station. When the pumps are turned on:
Step 1: Check the normal signs of the 4 pumps first, and start only the normal pumps.
Step 2: When the number of normal pumps is greater than or equal to 2, start the 2 pumps with the smallest number of starts.
Step 3: After starting the pump, add 1 to the number of pump starting. Then loop.

How to write in a loop?

booook

for (int i=0; i<=3; i++)
{
    if (Pump[i].IsNormal())
   {
        NumOfNormal++;
        NormalPumpArray.Add(Pump[i]); // pass the reference
    }
}

SortByStartTimes (NormalPumpArray);

if (NumOfNormal>=2)
{
       for (int j=0; j<2; j++)
       {
            NormalPumpArray[i].StartUp();
            NormalPumpArray[i].AddCount(); // it's better to add count in StartUp function
       }
}
else
{
      for (int j=0; j<NumOfNormal; j++)
     {
            NormalPumpArray[j].SartUP();
            NormalPumpArray[j].AddCount();
     }
}

Probably write it, think carefully for yourself

Then what does it mean to loop?
Continue to start the others? Then it might as well start all at once.

Maybe the host wants to implement something similar to a worker thread, which is to keep the pump in working condition.

I can't understand how I look at it!
