[algogeeks] Re: Give Algo to do this in O(n)

2011-10-10 Thread sravanreddy001
Without sorting the elements we have around n^2 elements to look from, to 
find the smalled element.

But, after sort, we will have only n-1 elements to look from. So, O(nlogn) 
is what I see, the best case.

Is there really a O(n) solution, as finding the diff between elements should 
be done comparing will every other. (unsorted)
or selected ones (after sort)

A radix sort would provide an O(n) solution for any fixed-size integer
data type.
