Ignoring payload size, what is relative difference in latency between an in-proc call (say in C++ or Java), a socket call to a process on the same machine, and a socket call to a process on another machine? This can be expressed as a minimum latency in ns/ms or in terms of relative orders of magnitude. I'm looking for something similar...
I have been trying to tackle this problem, but I am having difficulty understanding it: Let φ be Euler's totient function, i.e. for a natural number n, φ(n) is the number of k, 1 <= k <= n, for which gcd(k,n) = 1. By iterating φ, each positive integer generates a decreasing chain of numbers ending in 1. E.g. if we start with 5...
I'm designing an algorithm to do the following: Given array A[1... n], for every i < j, find all inversion pairs such that A[i] > A[j]. I'm using merge sort and copying array A to array B and then comparing the two arrays, but I'm having a difficult time seeing how I can use this to find the number of inversions. Any hints or help would ...
All objects in my program inherit from a Container class. The Container class has a virtual BaseNode* getParent() const; method and a virtual void setParent(BaseNode *p); method. I have a Set class (Set in a tennis match, not a data structure) which has the Match class as it's parent (via setParent()) but since Set inherits from Contai...

I want to calculate what is $x percentage of a $total. $x could be 15%, 20%, etc, and $total could be 1000, 2000, etc. So I'd want the 15% of 1000, for example. What is the formula for calculating this? (I know this isn't exactly a coding question but I'm coding this feature and need help! ...

Hi guys I want to create a program that requests from the user 10 grades and then filters them to pass and fail, then prints the number of passes and fails. I did the program but the output is wrong. int pass,fail,grade,studentcounter; pass=0; fail=0; grade=0; studentcounter=10; while (studentcounter!=0) { printf("enter the next ...
Hi guys I'm a junior student and I had a course called The Design and Analysis of Algorithms,The course is cool but the instructor is not any way, I dont understand the brute force and how to count the number of operations and how to count the time complexity(worst,best,avg), I tried to search for it on the net but each time I end with ...

My professor assigned a project where a simulation is ran through a GUI. To edit it, we need to create a "New" menu item. We haven't learned how to get data from a GUI, and our book does not cover it at all. What I'm trying to do, is when the "New" command is hit, focus gets shifted back to the CMD prompt, where System.out. starts work...
Hi, I'm designing an algorithm for class that will determine if a graph is unique with respect to a vertex v such that for any u <> v there is at most one path from v to u. I've started by using BFS to find the shortest path from v to another vertex u, and then running BFS again to see if an alternate path can be found from v to u. I th...

Can any one explain why the output of this code is only 'hello' and what this code means? ( 0, characterArray, 0, characterArray.Length ); The output is showing: The character array is: hello The code follows: string string1 = "hello there"; char[] characterArray = new char[ 5 ]; string1.CopyTo( 0, characterArray, 0, characterArra...
I have been working on a Java project for a class for a while now. It is an implementation of a linked list (here called AddressList, containing simple nodes called ListNode). The catch is that everything would have to be done with recursive algorithms. I was able to do everything fine sans one method: public AddressList reverse() L...

Hi everyone, here's the deal. For my project I have to serialize and deserialize a random tree using Java and XStream. My teacher made the Tree/RandomTree algorithms, so I don't have to worry about that. What I don't know how to do is this: I am using FileInputStream to read/write the xml file that I serialized and deserialized, but ...
I am stuck on this problem which I am studying for an exam tomorrow. (I understand the concept of virtual vs. physical addresses, page frames, address bus, etc.) If you're using 4K pages with 128K of RAM and a 32 bit address bus, how large could a virtual address be? How many regular page frames could you have? EDIT: I believe the ans...
