Re: [algogeeks] Most Optimal Palindrome?
You don't need to reverse anything. You reverse half the number and then compare positions, why not just compare things straight away? Also note that your solution is not n/2. Should the length be n it would be at least n operations. n/2 to reverse half the string and then n/2 comparisons. However, your method is depedent on the number of digits in a number and a number n does not have n digits in it, it will be approximately log n.

Re: [algogeeks] Re: Implement lastindexofastring(String s1,String s2)
What I suggested is optimal and doesn't require you to reverse the strings. It's not hard to see that it takes O(n + m) which cannot be improved on.

Re: [algogeeks] Re: Printing all inversions in an array
That statement is only very superficially similar. Counting them is saying how many of them there are, it doesn't necessarily require you to look at/compute each one. So it is not the same as printing them. If you're saying I want to print out each inversion individually then it's going to be n^2 and there's no way around it. If you have some other encoding so you can print something which represents multiple inversions in 1 step, you might be able to get under n^2.

Re: [algogeeks] all subarray with sum zero
Because you sort the array you may have values such that the indices are in the wrong order e.g your 'end' position is less than your 'start' position. You need to check for this, however if you use an inplace sorting algorithm this becomes easier. Additionally you may have up to O(n^2) occurrences so when you say 'now check for consecutive value which have same value' you should do a binary search for the end position instead. If you do as you said you may take O(n) per search. You want to report the ranges to avoid having to have report each occurrence.

Re: [algogeeks] O(n) solution is there or not!!
Oh, I actually read the question totally wrong. I think this idea is linear, but it's late so I'm not sure. 1. Calculate suffix array and lcp array for the text. 2. Calculate the longest common prefix between your text and the first entry in your suffix array and initialise a variable called total with this value and another variable called last. Last is a variable to store the lcp between the text and the last suffix you considered. 3. Now traverse the suffix array using the lcp array. for some point, i, if the lcp between the text and the last entry is lcp[i+1] you can do total = total + lcp[i+1] if the lcp between the text and the last entry is lcp[i+1] you can do total = total + lcp[i-1] if the lcp between the text and the last entry is = lcp[i+1] you need to do some more work and try and extend the match from position lcp[i+1] I think that should be linear though? correctme if i'm wrong.

Re: [algogeeks] Re: Algm
Heapsort and any other comparison sort have a lower bound of O(nlogn). Radix sort gets around this as it isn't a comparative sorting algorithm. It instead groups numbers by their significant digits (keeping original order), normally by count sort as mentioned above. Applying this for each significant digit will get you a sorted list in O(n) time.

Re: [algogeeks] Re: How to check whether a language isTuring Complete?
Somewhat; HTML, CSS and SQL aren't programming languages anyway, they're markup, style sheets and query languages respectively. TXL would be an example of a programming language which isn't turing complete but can still do something. Being able to compute something doesn't make it turing complete, being able to compute anything which it is possible to compute is what makes it turing complete. On 28 March 2011 17:42, Karthik Jayaprakash howtechstuffwo...@gmail.comwrote: Thanks for your reply. I understood lot better than I was previously. So summing up your answers, A language is turing complete, if we can write infinite loops and primitive recursive function. Some of the non turing complete languages that I came across are HTML, CSS, SQL... From this can I assume, that a language is turing complete, if it computes something, rather than just trying to display a interface, or pull records. Coz languages like HTML CSS doesnt do anything to compute something, it just transforms one way of representation to another(HTML - browser readable code), where as C,C++ can compute something and can represent large mathematical problems.

Re: [algogeeks] Re: Serialization in BT
If it's in array representation the simplest way is just serialise the array?

Re: [algogeeks] Re: 1s and 0s
This is simply a decision problem is it not? the above sorting would require n log n for comparison sorting where as a decision could be simply done in linear time and space.
