I'm creating a simple calculator program and that's all well and good. It's coming along smoothly except for the problem I have with parsing this string to double. public class DoubleParseWithAsterisk { public static void main(String[] args){ String str = "*2.3"; char c = str.charAt(0)...

Where can we declare static variables? I have learnt that it should be declared in the class level but are there other fields where we can declare them or just in class.

Question: A country X consists of N cities numbered 0 to N-1 . The map of this country can be represented as a cycle — for each valid i, city i has exactly two neighboring cities (i+1)%N and (i-1+N)%N. The cities in the country are broadly categorized into different types. For each valid i, the ...

Why is the output of the following code i=10 j=0 Why doesn't j gets initialised to 10? class MyClass{ static int j=func1(); static int i=10; static int func1(){ return i; } public static void main(String[] args){ System.out.println("i="+i); System.out.println("j="+j); } }

Ok, so here is the problem state : At input you have two integers : n representing the number of chars at input, and k , and after that n chars of string. Something like this : 6 0 ban?na Task is to find number of these strings when we replace the ? that fits the condition abs(number_of_vowe...

I have a working example of a piece of code which opens up a file, gathers information about the contents, and outputs a map which contains the information. The file The file type is an in-house creation, called an Xsam file. For those interested, it's based on the sam file, which is used commo...

For the last couple of hours I am struggling with char pointers in c. I am trying to get the user input as characters and store the characters as array members and I want to allocate memory for the array using malloc. Here is my code: #include<stdio.h> #include<stdlib.h> int main() { char* a...

To learn about Perl 6 grammars, I created a simple parser for C source files. Note that this is a constructed example motivated by this question. The point is to parse a C source file and correct user typos in argument lists. #! /usr/bin/env perl6 # # Correct user typos in a C source file accord...

I am trying to write my own function to split a String into many substrings of a given length in Haskell. For example, "split 5 "abcdefghijklmnopqr" " would return a list of strings ["abcde","fghij","klmno","pqr"]. I have gotten as far as writing the type signature "size :: Int -> [Char] -> [[Cha...

I am given N buckets each filled with f[i] units of water (where i is for ith bucket). I need to find the minimum amount of water(in units) say X that can be taken out of a bucket in each hour so that all buckets are empty in H hours. Suppose I take X units of water per hour. Each hour, I will ch...

I think that what i'm doing here is kind of overkill and there is better and clean approach to do it. ngOnInit() { this.activatedRoute.paramMap.switchMap( (params: ParamMap) => { return of(params); }).do((params) => { if (params.has('opportunityGuid')) { this.opportunityGuid = new Gui...

I have to parse a custom configuration file with these structure: # Begin with core containers. ID = 0 # STX container Name = "" # No name is necessary for a STX container. Flags = {STX} Attributes = {Status=0} So I've written the following code in order to remove those...

I'm not a dev, more like a designer. I have a calendar on two different pages, and it should behave differently one these two pages. So I modified the code a bit for it to happen, and it did when I tested it. BUT now I have to integrate both these variants together and of course gulp can't compil...

I wrote an extension method that takes a custom object and converts its properties to a query string for use in a URL. You can specify what properties you want included by using a [QueryString] attribute. For example: class Thing { [QueryString] public int Id {get; set;} [QueryStrin...

This works, and does what I want, but it feels ugly and clunky to me. How can I make it better? It's just constructing a basic lisp-style list and pretty-printing it. // simple example of pattern matching on Rc<enum> use std::rc::Rc; use std::fmt; type Cell = Rc<RawCell>; #[derive(Debug, Clo...

I'm currently writing a Miller-Rabin primality test using C++ and the GNU MP Bignum Library (GMP). As I've only started learning C++ about a day ago, I'm sure this code is riddled with errors and inefficiencies. I'm looking for several things (in order of importance): Make the code as fast as p...

I was curious a few weeks ago about how surnames come and go (mostly on the go). I wanted to know how quickly surnames die out, because (in my simplified simulation world) once the last person with a surname dies, it's gone forever. I started writing a small simulation to see this happen in "real...

There's loads of questions on SO about what the c# equivalent is of the useful VBA/Access "NZ" function. It accepts a parameter, and returns an alternate value if the parameter is null. It saves having to CONSTANTLY do "??" AND "==System.DBNull.Value" checks. In other words, those hundreds of li...
