I'm making a program that compares Multi-key sequential search and Interpolation search in a sorted array by the number of array accesses for my assignment. The current code is as follows: /* * A program that compares Multi-key sequential search and Interpolation search in a sorted array by the...

I am just starting to learn how to program in Python for my intro to programming class. The assignment is to prompt the user for a search word and then search the file, Text_File.txt for the search word and compute the percentage of times the word occurs in the document, e.g. if there are 300 wo...

I am trying to determine the number of factors of a large number efficiently. I have written this function but how can it be improved upon? long numOfFactors(long long n) { long i=0,num=0; for(i=1;i<=n/2;i++) { if(n%i==0) num++; } return num; }

I've spent my fair share of time criticizing other people's code on this site; but I'm finding out I'm kind of a hypocrite. Almost everything I've written so far has been some program whipped together to do some task for me. I have little experience actually starting out writing maintainable code...

This is for a single producer and single consumer wait free ring buffer. The writes need to be wait free for sure. It pre-allocates messages slots and uses a claim strategy to capture a buffer for write or read. For writes, it uses a ping pong strategy if the buffer is full which means if it find...

For many Optimisation methods the parameters must be given as a single vector (Eg Optim.jl). But for many interesting functions the parameters/coeffients to be optimised are matrixes, or a mixture of matrixes and vectors. Often this mix can be put into a composite type. I got sick of rewriting m...

I was bored, and looking to do something that involved anonymous functions, and it was suggested by @Quill, that I create a summation function. I decided to also include a product function as well to top the whole thing off. For those who don't know, a summation is usually defined like this: ...

First time poster. I'm working on an XNA project that loads several resources that are packed into a single file. XNA can take a WAV file stream and turn that into a SoundEffect (seen below in "case ".wav""). Since WAV files are large, I want to enable MP3 audio as one of the resources, so I ...

I recently gave a test on HackerRank, and submitted my answer for the following question. I passed all the test cases but company told me that the answer is not efficient, and they are not moving forward with my candidacy. I don't have a screenshot of the question, so will explain as much as po...

How can I locate and remove a Node from a LinkedList that has only “head”? It does not have any tail, current, header, trailer and counter. I also want to throws a “NullPointerException” if this list is empty. And return true if supplied value found and removed; else returns false

This question was my exam question: Locate and remove a Node from a LinkedList that has only head. It does not have any tail, current, header, trailer and counter. I also want to throws a NullPointerException if this list is empty. And return true if supplied value found and removed; else returns...

How can I find the sum of the 3 largest numbers in an unsorted array without using any kind of sorting function. Here's the code that I wrote using the qsort() function in C. Choice of language is no barrier, although I'd prefer C, C++, C#, Java or Python. #include <stdio.h> int array[100]; int ...

I have the following code To get the prime numbers between a range of numbers, is this the best and fast method? int[] numberCollection = Enumerable.Range(startNum,Count).ToArray<int>(); string primeNumbers = string.Join(",", from number in numberCollection ...

We generally don't allow design-only questions. A question has been asked that provided review-able code, and depending on your POV an additional question is asked about 'maintainable modular code' in general. Now, that is definitely more design-related than code-related, and in my answer I have...

I'm building a Markov text poetry generator. The main method, which is attached below, performs a depth-first search through the Markov chain, which is implemented as a NetworkX digraph of Word objects, which have methods for determining whether e.g. a Word rhymes with another Word instance. At...

I have a text file composed of several subsequent tables. I need to get certain values from certain tables and save them in an output file. Every table has a header which contains a string that can be used to find specific tables. The size of these text files can vary from tenths of MB to some GB...

Problem 62 of Project Euler goes The cube, 41063625 (3453), can be permuted to produce two other cubes: 56623104 (3843) and 66430125 (4053). In fact, 41063625 is the smallest cube which has exactly three permutations of its digits which are also cube. Find the smallest cube for which...

I have two separate jsp pages. in both of them, I define a page variable, in the uppermost level of the javascript. Then I set the variable, by parsing an incoming json string. Both of them appear perfectly as excpected, when performing an immediate console.log, but one of them is once again und...
