Given two numbers, print a page with an "X" in the specified location (±10%).
The numbers must be either percentages or fractions of the page's print area dimensions, e.g. [25,75] or ["15%","0%"] or [0.33,1]. You do not have to consider margins. Just remember to state which number is width, and ...
Task:
Given sample index, x, calculate sample value f(x) of triangular wave, with period of 4 samples and amplitude 1. Offset can be negative and sample value could be either {0, 1, -1}.
Test cases:
-5 -> -1
-4 -> 0
-3 -> 1
-2 -> 0
-1 -> -1
0 -> 0
1 -> 1
2 -> 0
3 ->

Introduction
I like to think programmers are inherently good people, even if some aren't so nice, so lets help people make sure they are protected with the MS17-010 patch.

Your challenge is to write a full program or function that returns a truthy or falsey v...
Convert ambiguous dates to "the correct way" (YYYY-MM-DD)
A problem I run into often with spreadsheets of data is dealing with dates of unknown ordering.
Your task is to take a series of dates that are in one of the following three formats, and output them as YYYY-MM-DD:
DD/MM/YYYY
MM/DD/YY...

In this challenge, you should write a program or function which takes no input and prints or returns a string with the same number of bytes as the program itself. There are a few rules:
You may only output bytes in the printable ASCII ran...
The Task
This is my first challenge so apologies if it is very simple! In this challenge, your task is to write a program or function which takes in a list of integers and a desired sum and outputs a truthy or falsey value based on whether the list contains two numbers that can be summed togeth...
The Game
This game is an adaptation of a board game called Mammut, and basically an optimization problem.
Each match contains five players and five rounds, in which every player participates. Every round starts with a bunch of tiles being flipped at random on one of their sides, and put in the ...
Set The Shapes

Challenge
Given an integer n and 2 other integers representing different shapes, output a set of the first n numbers of both shapes in ascending order.
Input
3 integers, n, s & t where:
n>0
2<(s<>t)<11
The values of s & t each represent a diff...
It is part of a Gauss quadrature formula.
I have the weights and the nodes for the range [0,1].
But I need the nodes and weights in for the range [a,b].
I have to use a special formular.
So I only have the option to change the weights and nodes.
I think:
for the weights:
new weight = ((b-a)...
I have a large collection of fine art. My toddler is learning to use scissors and glue; lately she has started playing with my art collection. Fortunately she is really quite good with the scissors and cuts things up into perfect squares. She then uses glue to randomly tile the cut-up squares ...
Your challenge is to play some variation of these chords:
C
Am
F
G
It forms a common tune that is heard in a lot of music.
You may also play transpositions:
F
Dm
A#
C
You can play the notes in any format. This is allowed:
C
A
F
G
And so is this:
C
E
A
C
F
A
G
