I have a field which takes values from 0 to 6,00,000. For this field values in database are say 5,6,7,8,45,91,92,93,94. I have to get free values and used value suggestions for this field. 1.USED Minvalue= 0 maxvalue=94( from database) i use a for loop (i=minvalue;i<=maxvalue;i++) Loop runs 94 times in this case and each time it checks if something matches database entries (5,6,7,45..94). I print output ranges like. Used values: 5 to 8 45 91 to 94 Since values are less it works fast. If there was even one entry like 490000 in database then loop would have run for a very long time. 2. FREE Min value= 0 maxvalue = 600000 (from field definition) I have the same for loop concept here too so the loop runs 500000 times. And output comes after a long time. It is too time consuming. I would want output like. Free values : 0 to 4 9 to 44 46 to 90 95-600000 Any way to reduce for loop executions or use some other logic.
