I am having a hard time trying to understand some of the design patterns, particularly the differences between some of them, such as proxy, delegate and adapter. Since design patterns are supposed to
I have to determine whether a language (for example L={a^n b^m c^s | 0<=n<=m<=s}) is regular, context-free, recursive, recursively enumerable or none of them.
First off, I would like to mention the question is a homework question. I have been pondering about the implementation for long enough.
Is there any practical开发者_StackOverflow社区 algorithm for generic elements (unlike counting sort or bucket sort) that runs faster than O(n log n)?Many people have mentioned the information-theoreti
Given an unsorted list in an array, will it necessarily take at least linear time to 开发者_JAVA百科find the number of elements smaller than x? If so, why?Yes, you would need to examine every number a
I\'m writing an AI for an RTS game, using the API the game offers. One thing I want to do is determine a set of line segments bounding the enemy nation, However, the game only offers a function which
I have this problem that I can\'t solve.. what is t开发者_如何学Pythonhe complexity of this foo algorithm?
In Computer Science, it is very important for Computer Scientists to know how to calculate the running times of algorithms in order to optimize code. For you Computer Scientists, I pose a question.
Regular expressions are often pointed to as the classical example of a language that is not Turning complete. For example \"regular expressions\" is given in as the answer to this SO question looking
What are \"source-level statements\"? \"Algorithm determines both the number of source-level statements and the number of I/O operations executed\" from Computer 开发者_C百科Organization and DesignSt
