Update (in response to first answer, from Hans Passant): I guess I didn\'t explain my use-case well enough. This application will be designed for people to enter data in a \"master\" language (most l
What is the \"good\"开发者_JAVA百科 (and why ?) solution to get a List from a Set and sorted against a given Comparator ?Set<Object> set = new HashSet<Object>();
Currently I am studying Standard Template Library (STL). In this program I am storing some long values in Associative Container and then sorting them according to unit\'s place (according to the numb
I have a sorted set (std::set to be precise) that contains el开发者_如何学运维ements with an assigned weight. I want to randomly choose N elements from this set, while the elements with higher weight
I am playing with python and am able to get the intersection of two lists: result = set(a).intersection(b)
I have a list of products {P1, P2, ...} each of which can have a list of attributes {a1, a2, ...}. What\'s the fastest algorithm to find all elements NOT having some attributes say {a2, a6, a10}?
I am looking for the solution of following algorithm with minimal time and space complexity. Given two arrays a and b, find all pairs o开发者_运维百科f elements (a1,b1) such that a1 belongs to Array
Why does the iteration order of a Python set (with the same contents) vary from run to run, and what are my options for making it consistent from run to run?
I have inherited a mapreduce codebase which mainly calculates the number of unique user IDs seen over time for different ads. To me it doesn\'t look like it is being done very efficiently, and I would
