Homework Answers
Ans.)Each IP address is a 32 bit, 4 tuple address as <x1,x2,x3,x4> where xi={0,.....,255}
therefore, hashing will be as:
ha=(x1,x2,x3,x4)= a1x1+a2x2+a3x3+a4x4
| Data | hashed value |
| 209.85.231.104 | 209 x 1+85 x 2+231 x 4+ 104 x 5=1823 |
| 207.46.170.123 | 207 x 1+ 46 x 2+170 x 4+123 x 5=1594 |
| 208.80.152.2 | 208 x 1+80 x 2+152 x 4+2 x 5=986 |

Insert elements into a hash table implemented using chain hashing, as an array of linked list in which each entry slot is as a linked list of key/value pairings that have the same hash (outcome value computed using certain hash function). You are allowed to use “Hash Function”, h(k) = k % x where, x is the value you will need to decide to use, that you find appropriate for this implementation. The main requirements are the following: 1. Input:...

1. Using closed hashing with double hashing to resolve collisions insert the following keys into a table with 11 slots, numbered 0 through 10. The hash functions to be used are H1(k)k(mod11) and H2(k)- Rev(k + 1) (mod11) The function REV reverses the decimal digits like Rev(376) 673. Show the hash table after all nine keys have been inserted. Be sure to indicate how H1 and H2 are used. Keys: 4, 3, 2, 8, 33, 17, 24, 35, 46
