Nettet1. Division Method. If k is a key and m is the size of the hash table, the hash function h () is calculated as: h (k) = k mod m. For example, If the size of a hash table is 10 and k = 112 then h (k) = 112 mod 10 = 2. The value of m must not be the powers of 2.

Linear probing will look for an element until it hits an empty hash bucket. In this case, it will examine 8, 9, 0, 1 and 2; at 2 it will stop because the bucket is empty. Note that deletion is handled by replacing a bucket with a special "tombstone" value which marks the element as deleted but avoids breaking a linear probe chain. … ship crews abandoned
