Alain Colmerauer designed the logic programming language Prolog. His goal was to create a programming language that is as intelligent as a two-year-old child. In order to prove t...
Observability and controllability

Background
Note: if you like, you can skip this part, and simply implement the suggested algorithm.
When looking at dynamic systems, there exist the notions of observability and controllability. They are the answers ...
Your task is pretty simple. Given two floats, bitwise xor the binary representation of them, and output that as a float.
For example,
Normal: 16.7472 ^ 123.61 = 7.13402e-37
Binary: 01000001100001011111101001000100 ^ 01000010111101110011100001010010 = 00000011011100101100001000010110

Solve a separable differential equation
A first order separable ordinary differential equation is (arguably) the easiest type of differential equation to solve, and takes the form of
$$N(y)\frac{dy}{dx} = M(x) \\
y(x_0) = y_0$$
For two given functions \$N(y)\$ and \$M(x)\$ and an initial cond...

When represented in base three, there are some integer powers of two where the digits are a permutation of the next power of two.
Some examples:
\$2^5\$ in base three is \$1012_3\$, whereas \$2^6\$ in base three is \$2101_3\$, both have one \$0\$, two \$1\$’s, and one \$2\$
\$2^{27}\$ → \$1001...Anonymous
Challenge
Given an array of positive integers and a threshold, output grouping sets of consecutive elements (subarrays) such that each group/subarray has a sum greater than the threshold.
Rules
The solution should honor two additional criteria:
be of highest cardinality of the groups (i.e. h...0
Cleaning the dishes
In this task, you will be given a bar of soap with a width of 1 or more units, which will be inputted as an integer. You will also be given a plate, which you will have to clean, using the soap as few times as you can. The plate will be inputted as a an array of 2 different c...
