Given a phrase, count the occurrences of each word in that phrase.
Calculate the number of steps to reach 1 using the Collatz conjecture.
Calculate the number of grains of wheat on a chessboard given that the number on each square doubles.
Scheme supplies a small number of general-purpose features.
Inspired by lambda calculus, scopes and loops are expressed by defining and calling functions.
Some applications use Scheme as their extension language.
Both source code and data are expressed using nested lists.
Scheme supports exact and inexact numbers.
Scheme supports hygienic macros, allowing the syntax to be extended reliably.
Every language has its own way of doing things. Scheme is no different. Our mentors will help you learn to think like a Scheme developer and how to write idiomatic code in Scheme. Once you've solved an exercise, submit it to our volunteer team, and they'll give you hints, ideas, and feedback on how to make it feel more like what you'd normally see in Scheme - they'll help you discover the things you don't know that you don't know.
