Am I wondering if the follow are true. If f(n) is开发者_如何学Python O(g(n)) and f(n) is also Ω(g(n)) that means
Can someone explain this to me? Such as this: Given a function: for k = 1 to lg(n) for j = 1 to开发者_如何学Go n
I have a variable number of ArrayList\'s that I need to find the intersection of. A realistic cap on the number of sets of strings is probably around 35 but could be more. I don\'t want any code, just
I have n=10000 10-dimensional vectors. For every vector v1 I w开发者_JAVA百科ant to know the vector v2 that minimizes the angle between v1 and v2.
This is for an assignme开发者_如何转开发nt, and is in psuedo-code. I need to find how many integers in an array are unique, nothing else, but it has to be in O(n), preferably without hashing.
How can you convert Binary Tree to Bi开发者_StackOverflow中文版nary Search Tree with O(1) extra space ?Converting an unordered binary tree into an ordered binary search tree is trivial, but a bit more
I had someone advise me to avoid repeatedly calling String.Length, because it was recalculated each time I called it. I had assumed that Str开发者_开发百科ing.Length ran in O(1) time. Is String.Length
How would you characterize the below in big-O notation? rotors = [1,2,3,4,5 ...] widgets = [\'a\', \'b\', \'c\', \'d\', \'e\' ...]
I\'m just not sure... If you have a code that can be executed in either of the following complexities:
I\'m reading a textbook right now for my Java III class. We\'re reading about Big-Oh and I\'m a little confused by its formal definition.
