Hi,I have looked at a lot of previous posts about how to effeciently remove duplicates OR detect duplicates in an array of integers, but unfortunately most of them are of O(n^2) time complexity orof O(n log n) time complexity with o(n) space complexityI was wondering if there is a faster ...

Been just messing around with several dozen sorting algorithms (was bored and this is what i do for fun). But I can't seem to find a good implementation of Batcher's bitonic sort. And I mean by "good", that it will work on all arrays, not just powers of 2 in length.Of course there are the ...

What kind of algorithm would you use to make this sort of program? I'm not too familar with doing something like this, so I wouuld like to see how you guys would do it.

They launched a probe today called "Deep Impact". It will attempt to smash into a comet to see what it is made of. Now, aside from the fact that it is ironic they picked the same name as a movie about an asteroid hitting Earth, guess when the impact is due to occur? The 4th of July. Cosmic ...

Hi! I need help.I have to create a java program that initialise a crystal object, run it and save the report to some where.I should then schedule the java program as a service in windows admin setup to run every day.

Can you help me by giving the function of that algorithm? SHA1PRNG. I've searched in the Java help but it just told it was built in. Does someone know what is the funtion of the SHA1PRNG. Does it have funtion such as Y=X mod 3 or something like that?Thanks for your help.....
