START STEP 1-> Take an array with elements, bool flag[MAX] to Fale, int i, j, n to size of array Step 2-> Loop For from I to 0 and i<n and i++ IF array[i] < 100 && array[i]>=0 Set flag[array[i]]=true End IF Step 3 -> End For Loop Step 4 -> Loop For from i to 0 and i<MAX and ++i IF flag[i] == false Set j=i+1 Loop While j<MAX && flag[j] == false Set j++ End While If j=i+1 Print i End IF Else Print i and j-1 End Else Set i=j End IF Step 5 -> End For Loop STOP
