Bkdr hash function
WebFeb 21, 2024 · 1. The hash function should be simple to compute. 2. Number of collisions should be less while placing the record in the hash table.Ideally no collision should occur. Such a function is called perfect hash function. 3. Hash function should produce such keys which will get distributed uniformly over an array. 4. http://www.java2s.com/example/java/java.lang/get-string-bkdr-hash.html
