I have an idea for a code-golf question and, in my opinion, I believe that it is quite a difficult problem to code in the first place, let alone to golf.
I've seen questions being closed for duplicates, being off-topic and others but was wondering if my question could be closed or put on hold fo...
Input: an integer N between 1 and 151
Output: the Nth Pokemon.
Rules
You may use one data file.
You may not use any already made data decompression algorithms. This includes libraries and other programs.
Your program may not access files other than itself and your data file.
Scoring
Your ...
Write a program that takes an input, reads a file and outputs the resulting answer. Easy, right?
Wrong. You may have noticed "Siri" in the title. Let's explore this detail even more: You are to become Siri. You are to write a function or program that takes a string as input (one of the questions...

The rundown
Create a program that generates an array of random length with random numbers, then apply a series of rules that alter the array. After the rules have been applied, print the sum of the array unless specified otherwise
Array setup
The array must be a random length between 5 and 10 ...

Task
Basically you have an array of random integers e.g.
I() = [1, 4, 3, 2, 5, 3, 2, 1]
and you have to create another array of the same length with the numbers 1 to the size of the array in place of the smallest to largest numbers respectively, e.g.
O() = [1, 7, 5, 3, 8, 6, 4, 2]
For dupl...
[2*r^6+3*r^5-4*r^4-3*r^3+2*r^2]*(diff(F(r), r, r))+[4*r^7+14*r^6-5*r^5-30*r^4+9*r^3+19*r^2+2*r]*(diff(F(r), r))+[16*r^7+8*r^6-28*r^5-12*r^4+8*r^3-2*r^2-2*r+4]*F(r) = 0
it is a second order homogeneous differential equation..suggest me some method to find its solution...
I was given to write a sage code to find out $\lambda$ determinant in Combinatorics.
Which is related to Dodgson's algorithm.
for 2 by 2 matrix with entries $a_11,a12,a21,a22$ we write $a_11 a_22 + \lambda a_12 a_21$
But I need code for n by n matrics.

Challenge
Given an input of an integer, n (where 0<n<50), output the graph of from x = -3 to x = 3 inclusive.
Where is the real part of the complex number p.
Note that
Output
The output may be in any form you wish (e.g. an image or a window etc.) but the graph must have axes. ASCII art i...
