I want to开发者_C百科 multiply two matrices but the triple loop has O(n3) complexity. Is there any algorithm in dynamic programming to multiply two matrices with O(n) complexity?
Heap Sort has a worst case complexity of O(nlogn) while 开发者_如何学JAVAQuicksort has O(n^2). But emperical evidences say quicksort is superior. Why is that?One of the major factors is that quicksort
I\'ve written a Javascript file, using jQuery, that I would like to perform run-time tests on.I\'ve never done this before and was just curious on how to go about it.One site I visited suggested this
开发者_运维问答What is the difference between O(n^2) and O(n.log(n))?n^2 grows in complexity more quickly. Big O calculates an upper limit of running time relative to the size of a data set (n).
Thanks to everyone replying with ideas and alternate solutions. More efficient ways of solving problems are always welcome, as well as reminders to question my assumptions.That said, I\'d like you to
This question already has answers here: Closed 13 years ago. Possible Duplicate: are there any O(1/n) algorithms?
I have this question, and I don\'t know how to solve it, because I don\'t understand it. :( The question is:
