To cite a recently sandboxed challenge by l4m2:
Solution win if there's no strictly better solution, aka. no solution that take less or same amount of items in mapping table, less or same amount of instrucions, and at least one of amounts of items and instructions is less.

One thing that is constantly frustrating when golfing ARM Thumb-2 code is generating constants.
Since Thumb only has 16-bit and 32-bit instructions, it is impossible to encode every immediate 32-bit value into a single instruction.
Additionally, since it is a variable length instruction set, some...
Return all elements around an index forming sun
Define a function in python that takes in a 2D array and a 2D index, and return all the elements of the 2D array that are directly vertical to, horizontal to, and diagonal to the given index, and the returned list must omit the index itself.

I have a list of n numbers. I want to divide the list into sub lists, such as the sub list consists of continuous increasing numbers or continuous decreasing numbers. Then take the product of each sub list's min value and it's length. Finally take the sum of all this product's

l = [1,2,6,4...
Repost and improvement of this challenge from 2011
A vampire number is a positive integer \$v\$ with an even number of digits that can be split into 2 smaller integers \$x, y\$ consisting of the digits of \$v\$ such that \$v = xy\$. For example:
$$1260 = 21 \times 60$$
so \$1260\$ is a vampire nu...

The task is simple. Define the basic operators (+, -, *, /) without using them directly.
Shortest code wins
ASCII characters are all Unicode characters with code points from 0x00 to 0x7F (both inclusive).
Printable ASCII characters all are Unicode characters with code points from 0x20 to 0x7E (both inclusive). This does not include linefeeds.
This is consistent with the definition of printable charac...
