figure initial probe initial probe asuccessful search for bunsuccessful search for quadratic probes to see how quadratic probes lookstart up this applet and create new hash table of items using the new button when you're asked to select double or quadratic probeclick the quad button after the new table is createdfill it four/fifths full using the fill button ( items in -cell arraythis is too fullbut it will generate longer probes so you can study the probe algorithm incidentallyif you try to fill the hash table too fullyou may see the message can' complete fill this occurs when the probe sequences get very long every additional step in the probe sequence makes bigger step size if the sequence is too longthe step size will eventually exceed the capacity of its integer variableso the applet shuts down the fill process before this happens when the table is filledselect an existing key value and use the find key to see whether the algorithm can find it often the key value is located at the initial cellor the one adjacent to it if you're patienthoweveryou'll find key that requires three or four stepsand you'll see the step size lengthen for each step you can also use find to search for non-existent keythis search continues until an empty cell is encountered
