Most people would cut circular pizzas into circular sectors to divide them up evenly, but it's also possible to divide them evenly by cutting them vertically like so, where each piece has the same area (assume the pizza has no crust): Challenge Your task is to make a program or function that tak...

In this cops and robbers challenge, the cops will be tasked with writing an algorithm that computes some function of their choice, while the robbers will try to come up with their algorithm. The catch is, the 'algorithm' must be a single closed-form mathematical expression. Remarkably, a function...

This is the robbers' thread. See the cops' thread here. In this cops and robbers challenge, the cops will be tasked with writing an algorithm that computes some function of their choice, while the robbers will try to come up with their algorithm. The catch is, the 'algorithm' must be a single clo...
