String-wise calculus (i)
code-golfstringcalculus
This might turn into a series involving other aspects of calculus, including using the "derivative" of a string to find "stationary points" etc, as well as "integration" of sentences
Introduction
If y'all have ever studied calculus, you'll most ...
Iterative Quadratics
Recently, in my algebra class, we proved that the following process always stops at some point, so I thought it would be a cool challenge!
Input: Two reals a,b.
Output Non-negative integer
Challenge:
Given two reals a,b, initialize a count variable c to 0, consider the q...
Given a string of brackets tell the user whether or not the brackets are well matched or not. Brackets include []{}(). For example:
() <---- Well Matched
([{}][]) <---- Well Matched
({)} <---- Not Well Matched
({]) <----- Not Well Matched
This is a code-golf challenge so as always the shortes...
Please suggest a way to make a rotating line(like hands of clock)in python using turtle
Please help me I am a beginner!!
Context
After a challenge of mine asking you to compute a specific coefficient of polynomial multiplication, I wish to create a "mirror" one, asking you to compute a specific coefficient from polynomial division.
Polynomial division
Let us establish an analogy with integer division. If you hav...
Like if I have this:
x=5
y=2
and I do this
x,y=5,2
Do I call this simplifying or optimizing or something else? What is the terminology here.

Doubly stochastic matrix code-golf
A doubly-stochastic matrix is a square matrix of non-negative real entries each of whose rows and columns sums to 1. Given a doubly-stochastic matrix, express it as a non-negative linear combination of permutation matrices, as is guaranteed to exist by the Birk...
Add double-quotes (") in order to surround a word (i.e. something that matches [a-z]+).
[[one, two, three],
[one, two, three],
[one, two, three],
[one, two, three]]
Test cases
[abc,def,ghi,jkl] -> ["abc","def","ghi","jkl"]
this is a test -> "this" "is" "a" "test"
test -> "test...
def l(w,x,y,z):
f=-((-450+w+(2*x+y+z)*.75)//1)
return("Not bad w"if f>100else"W")+"ith your %.f%% as your score"%f
Any tips to golf this code so its not as long? Readability is not necessary here.
Essentially I take 4 floats and/or integers and calculate a fifth score needed in order ...
def l(a,b,c,d):
o=450.9-a-(b*2+c+d)*.75;return("Impossible, y","Y")[o>100]+"ou would need a %d%%"%o
Any general tips I could use? Or is this the shortest it's going to get.

Introduction to groups and fields
An additive group is a set with addition and negation defined. They must satisfy the following conditions:
\$0\$ is the additive identity.
Addition is associative.
For every \$x\$, the negation of \$x\$, \$-x\$ exists, and \$x + (-x) = 0\$.
