Young Coders: Week 3 Problem

-
EDIT: Just one extra Candy Challenge problem this week! 

 The full Candy Challenge = the following problem + two Candy Challenges from previous classes. 

 For those of you who have finished all the previous Candy Challenges, pick two problems from Week 2's 3,4, and 5, and try to solve them iteratively (with loops),  instead of recursively. 

 Write a toString() method for our Queue class that prints out its elements. 

 For example, 

public static void main(String[] args) {
   Queue animals = new Queue(); 
    
    animals.enq("Tiger");
    animals.enq("Pig");
    animals.enq("Zebra");
     
   System.out.println(animals); 
}

will give us {"Tiger", "Pig", "Zebra"}, not the hashCode() we have now (something like Queue@56ee20fe). 

 (An example: Look at the outline of a toString() method we wrote in the Pet class.)

Building A Toy Language Interpreter in Go

In this post, I'll be giving a high-level overview of interpreters, why they're interesting, and how they work. I'll be referencing my repo, go_interpreter , which is a simple interpreter written in Go for a toy language. The figure below shows the structure of our interpreter with an example input: What is an interpreter?  An interpreter is a language processor that seems to directly execute the source program on user input: In contrast, a compiler first takes in a source program and translates it to an executable machine code target program. Then, the user can pass in inputs to this target program and get outputs. In general, an interpreter is better at reporting errors since it's processing statements one at a time, and a compiler is faster at generating outputs from inputs. In this post, we're going to go over a simple interpreter that is capable of supporting: integers, booleans, strings, arrays, hashmaps prefix, infix operators index opera

Space Race: a simple Rust game built on the Bevy framework

When I saw a post announcing the release of the Bevy framework  (an open source game engine written in Rust), I thought it'd be a fun way to learn Rust.  So I made Space Race , a 2 player game on top of the Bevy framework. How to Play The Astronaut moves around collecting jewels (using WASD keys). The Alien moves around trying to catch the Astronaut (using arrow keys).  The Astronaut wins if they collect at least 5 jewels and make it back to home base before the Alien catches them.  The Alien wins otherwise.  Things I learned about Rust  I had a lot of fun making & playing this game, and also got some hands on experience with Rust like working with structs enums vectors iterators traits dyn trait vs impl trait  dyn trait is used for trait objects, which are fat pointers made up of 1) a pointer to the value 2) a pointer to a vtable. A vtable is a table of methods, where each method points to its implementation, generated once at compile time. Each instance of a type that impleme

Building a Toy Language Compiler in Go

A follow-up to my previous post about building a toy language interpreter in Go. Throughout this post, I'll be referencing my repo . We'll go over a compiler which translates source code to machine code, and then a VM to execute this machine code. What is a compiler?  A compiler takes source code and translates it to executable machine code . (See my previous post for more details.) The figure below shows the high-level architecture of a simple compiler. Like the interpreter we built previously, our compiler has a lexer and a parser which turn our source code into an AST . This is our compiler's frontend . However, that's where a compiler diverges.  The compiler may translate the AST into at least one internal representation (IR) . The IR(s) may be represented using any data structure (even another AST!), but they should follow two rules: (1) be easy to produce, (2) be easy to translate into the target machine code. The IR can also be optimized
