Document ID: 723vk4ufbbg-mgjxhm9i

This document contains a variety of concise, self-contained code examples across multiple programming languages, demonstrating common patterns, data structures, I/O, and control flow to exercise parsing in a realistic yet compact way.

Each example includes a short description followed by a fenced code block.

Where helpful, examples may include brief variations in syntax or structure so the parser encounters a wider range of constructs across different ecosystems.

Filters and projects a sequence using C# LINQ. Demonstrates expressive collection manipulation.

using System;
using System.Linq;
class Program {
  static void Main(){
    var nums = new[]{1,2,3,4,5};
    var squares = nums.Where(n=>n%2==1).Select(n=>n*n);
    Console.WriteLine(string.Join(",", squares));
  }
}

Counts files in the current directory using common shell tools.

FILES=$(ls | wc -l)
echo "Files: $FILES"

Julia list comprehension generating cubes of a range.

nums = 1:5
cubes = [n^3 for n in nums]
println(cubes)
