This question has already been discussed here.There are 4-5 methods to do this ,best is 'Moore voting algorithm' . refer: http://geeksforgeeks.org/?p=503 On Mon, May 31, 2010 at 10:01 PM, souravsain souravs...@gmail.com wrote: Hi All This is my first post to this community and so am

This is a different problem, where the requested number with maximum frequency is not necessary majority. On 2010-6-1 13:19, harit agarwal wrote: see this .vote majority algorithm.. http://userweb.cs.utexas.edu/~moore/best-ideas/mjrty/index.html

Hi All This is my first post to this community and so am exited. The problem is to find the no. that has maximum frequency in an array (size n) of integers. The approach to use a hash table, itereate through array (O(n)) and keep inserting into hash table (O(1)) and then scan the hash table
