Diophantine Circle
A Diophantine equation is an equation where only integer solutions are considered. For example, the equation x**2 + y**2 = 1 has infinitely many solutions, but only 4 integer solutions ((0, 1), (1, 0), (0, -1), (-1, 0)).
Given R > 0, output the number of solutions to the Diop...

The current system rewards writing documentation that is already covered by the official docs. Meanwhile, popular libraries without good official docs are undercontributed. The system is broken, and it needs fixing. This result runs counter to how Docs was pitched:

The set cover problem is a classical question in combinatorics, computer science and complexity theory. It is one of Karp's 21 NP-complete problems shown to be NP-complete in 1972.
It is a problem "whose study has led to the development of fundamental techniques for the entire field" of approximation algorithms.

Numerical Lookalikes
The task here is simple for a given number find how many other numbers share the same digits.
For example there is no other number that can be made out of the digits of 11 so 11 scores one. However the digits of 12 can also make 21 so 12 scores a two.
Lookalikes cannot ...

Can these rectangles be tiled?
Given a bunch of rectangles, you are asked whether or not they can be tiled to fill a rectangle.
Specs
Given a bunch of arbitrary m x n rectangles; 0 <= m, n <= 1000, determine whether or not it is possible to tile them so that they cover exactly a rectangular ar...

Inspired by that really weird quine challenge
For this challenge, you must choose three languages. (Sandbox: not sure if different versions of same language (Python 2 and 3) should be allowed) These languages will be referred to as X, Y, Z. For this challenge, you must write a progra...
How to fixed the sized of the sub region(table) to 100% in the oracle application.
What I am facing is that when any of the column in my sub reason(table) having many contents, then it occupy 100% width and if it having less content then sub region get shrinks, which I don't want.
Can any on...In computing, a polyglot is a computer program or script written in a valid form of multiple programming languages, which performs the same operations or output independent of the programming language used to compile or interpret it.
Generally polyglots are written in a combination of C (which allows redefinition of tokens with a preprocessor) and a scripting language such as Lisp, Perl or sh.
Polyglot markup is similar, but about markup language context.
Polyglot persistence is similar, but about databases.
== Methods ==
The two most commonly used techniques for constructing a polyglot program...

This challenge is the first in a two-challenge series about Repetition. The second will be up soon.
In a language called Repetition (something I just made up), there consists an infinite string of 12345678901234567890..., with 1234567890 repeating forever.
The following syntax is available to o...
