Interview Questions and Answers for 'Search' - 11 question(s) found - Order By Newest

Advanced level question frequently asked in US based companies. Recently asked in EMC and Intuit.
  Q1. Can you provide some implementation of a Dictionary having large number of words ? Solution
Admin
info@buggybread.com
Ans. Simplest implementation we can have is a List wherein we can place ordered words and hence can perform Binary Search.

Other implementation with better search performance is to use HashMap with key as first character of the word and value as a LinkedList.

Further level up, we can have linked Hashmaps like ,

hashmap {
a ( key ) -> hashmap (key-aa , value (hashmap(key-aaa,value)
b ( key ) -> hashmap (key-ba , value (hashmap(key-baa,value)
....................................................................................
z( key ) -> hashmap (key-za , value (hashmap(key-zaa,value)
}

upto n levels ( where n is the average size of the word in dictionary.

 Q8. How Cassandra provides better Read performance than Oracle Indices ?Database2017-08-18 09:39:56

Ans. Cassandra uses Hash Search which provides a look time of O(1) whereas Oracle Indices uses Binary Search that provide a lookup time of O(Log n).

 Q9. How different is the Search algorithm when we query Cassandra Tables and When we query Oracle Tables ?Cassandra2017-08-18 09:40:40

Ans. Relational Database uses linear search if we don't query using indices. Performance for linear search is O(n). If indices have been used , relational database uses binary search. Performance for binary search is O(Log n).

Casandra uses hash search. Performance for Hash Search is O(1).
