WebInsert algorithm uses the item's key to determine the initial bucket. 2. Insert linearly probes (or checks) each bucket until an empty bucket is found. 3. Item is inserted into the next empty bucket. 4. If probing reaches the last bucket without ±nding an empty bucket, the probing continues at bucket 0. 5. Because linear probing is especially sensitive to unevenly distributed hash values, it is important to combine it with a high-quality hash function that does not produce such irregularities. The analysis above assumes that each key's hash is a random number independent of the hashes of all the other keys. This assumption is unrealistic for most applications of hashing. However, random or pseudorandom hash values may be used when hashing objects by their ide…
