The program must load the data, process it, and output the results.
The output should look like the text box on the back page. The output should number the chess boards, starting at 1. For each board, show a text representation of the chessboard with the pieces printed in the correct positions. T...
Is this number part of a Collatz Prime sequence?
A Collatz Prime is defined as such:
$$p_{2} = \frac{3*p_1+1}{2}$$
Where p1 is the input prime, and p2 is the output.
Here are some test cases:
1 -> (3*1+1)/2 = 4 : false
3 -> (3*3+1)/2 = 5 : true
5 -> (3*5+1)/2 = 8 : false
7 -> (3*7+1)/...
Given a \$n\$-dimensional vector \$v\$ with real entries, find a closest permutation \$p\$ of \$(1,2,...,n)\$ with respect to the \$l_1\$-distance.
Details
If it is more convenient, you can use permutations of \$(0,1,...,n-1)\$ instead. If there are multiple closest permutations, you can outpu...
Randomize \$SL_n(\mathbb R)\$
Given a positive integer \$n > 1\$, return a random element from \$SL_n(\mathbb R)\$.
Details
\$SL_n(\mathbb R)\$ is the set of \$n \times n\$ matrices with determinant \$1\$.
In theory the output must cover the whole \$SL_n(\mathbb R)\$ (that is, if the RNG you'...
combine neighboring terms of the leibniz series weighted 3/4 : 1/4, move the leading 3/4 to the lhs (resulting in pi/4 - 3/4), then apply euler's transform to the remaining terms
@Mr.Xcoder And let's not forget our good friend: Someone randomly answered an old challenge of mine and bumped it, so now it's getting new answers and upvotes for a week
Find Magic Powers of Two
Represented in base 3, there are some integer powers of 2 where the digits are a permutation of the next power of 2.
Some examples:
2⁵ in base 3 is 1012, whereas 2⁶ in base 3 is 2101, both have one 0, two 1’s, and one 2.
2²⁷ → 100100112222002222 vs 2²⁸ → 2002010022210...
I can't think of a way to do it for unbounded inputs.
But for bounded inputs, the program is /a\A///A\a///b\B///B\b//.../z\Z///Z\z//, repeated a number of times equal to at least half the length of the input.
(Replacing ... with the appropriate code for C through Y.)

CMC: Generalised Quine: Given a black box function that takes in a character and outputs a value (that can be any type), output your program where every character has been passed through the function. E.g, if f(x) = lowercase(x) and your code was Ab123, you should output ab123. You can assume the function is implemented for all characters in your program (so no int(x) for non-integer characters etc.)
The challenge is to write a golf-code program that, given n positive real numbers from 0 to 10 (format x.y, y only can be 0 or 5: 0, 0.5, 1, 1.5, 2, 2.5 … 9.5 and 10), discard the lowest and highest values and shows the average of the remaining, in x.y format (y can be 0 or 5, rounded to closest)...
