Re: [algogeeks] Sorting in O(n)
+1 mithun kumar !! using bit array or bitmap index gives the best solution ( O(n) ) the only limitation is we should know the maximum limit of the number, which is provided in this problem :D Thanks Regards Saurabh Yadav -- You received this message because you are subscribed to the Google Groups Algorithm Geeks group.

Re: [algogeeks] Sorting in O(n)
After giving some thought,I think even radix sort may not be sufficient. Complexity of radix sort is O(k*n) where k is the number of buckets required to sort the given range. The number of buckets is proportional to the number of bits required to represent the *maximum number in the given range.*For our case the maximum number is O(n^2).Hence *the number of buckets required would be proportional to log(n^2) in the worst case.* Hence the worst case complexity for the given constraints using radix sort would be *O(n*(log n^2)) = O(n*logn).* This is no better than comparision sort.A slight optimization that we can make is to use a higher base which would reduce the number of buckets required but would add the cost of converting each number into the higher base. Somehow I am getting convinced worst case O(n) algorithm may not be possible.Working on the mathematical proof.

Re: [algogeeks] Sorting in O(n)
Hi all, I am new to this group. My last post was deleted i do not know the reason behind it. I will explain my logic here:- as the range is 1 to n^2 we have a input array like input[n^2]. We can take a auxillary array of size n^2 like aux[n^2]. Scan the input array. For each input input[i] increment by one corresponding aux[input[i]]. After this just iterate through the aux array printing the index aux[i] times. This way we can sort it in O(n) time.

Re: [algogeeks] Sorting in O(n)
Consider the case
n=6
array elements :-
{36 36 36 36 36 36}
How many iterations your code makes?
Consider another case
n=100
array={1e12,1e12 ..repeated 10^6 times}
How many iterations your code make?
Are the iterations still proportional to n that is the number of elements
in the array?

Re: [algogeeks] Sorting in O(n)
counting sort ll help to some extent... find the min and max element O(n) now u just need an array of size max-min to store the values then just traverse the list and while updating u do value+min... still it is not suitable if the magnitude is high.
