👉 In mathematics, a "jonque" is a function that takes as input two real numbers and returns an integer. The output of the function can be any number between -1 and 1. This means that for every input, there are exactly two possible outputs.
For example, if we have a function called `f(x) = x^2`, then for each value of `x` in the domain (-1 to 1), we get an output of either 0 or 1
