Document ID: 7x4jtgoqxwv-mm8c4cds

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.

Simple R vector example computing squares of a sequence.

squares <- nums^2
print(squares)

SQL query that groups by name and orders by count descending.
