Answer:
You can simplify the problem down by recognizing that you just need to keep track of the integers you've seen in array that your given. You also need to account for edge cases for when the array is empty or the value you get would be greater than your max allowed value. Finally, you need to ensure O(n) complexity, you can't keep looping for every value you come across. This is where the boolean array comes in handy. See below -
public static int solution(int[] A)
{
int min = 1;
int max = 100000;
boolean[] vals = new boolean[max+1];
if(A.length == 0)
return min;
//mark the vals array with the integers we have seen in the A[]
for(int i = 0; i < A.length; i++)
{
if(A[i] < max + 1)
vals[A[i]] = true;
}
//start at our min val and loop until we come across a value we have not seen in A[]
for (int i = 1; i < max; i++)
{
if(vals[i] && min == i)
min++;
else if(!vals[i])
break;
}
if(min > max)
return max;
return min;
}

Answer:
a. Power cycle the printer.
Explanation:
Power Cycle: To unplug the printer and restart it, is called power cycling. The peripheral devices often tend to stop working and the cause of this is not always easily figured out. So the first and easiest way that can be done to fix this issue is to run a power cycle. For this, you have to turn off the printer and unplug it. Then wait for a few seconds (at least 30) and plug in the printer again. Turn the printer on. Power cycle helps to resolve many basic issues. It is the easiest step to take before checking the printer cable, reinstalling printer or resetting the print spooler.
