Day 4: Rust Functions and loops
Today I’m looking at functions and loops. They are an important part of any language and deserve a closer look.

Day 3: Rust Variables and Data Types
Today I take a look at Rust variables and data types. It’s a gentle introduction to a language not too alien from JavaScript.

Determinant
In mathematics, a determinant is a special number that you can calculate for square matrices. It’s special because it is only nonzero if and only if the matrix is invertible and the linear map represented by the matrix is an isomorphism. That’s a lot of big words don’t you think? For today’s problem, we don’t…

Add function
Today we have a quirky problem that requires knowledge of higher-order functions, recursion, and advanced language features. It’s an add function that returns an adder function. Add Function Problem The problem is to create a function that will add numbers together when called in succession. Example It should chain as many times as we want…
