We're continuing to help Santa and his elves in their big preparation and push for Christmas with Advent of Code Day 2!

This canvas solves the Advent of Code Day 2 challenge by identifying and summing "invalid IDs" through two distinct algorithms: Part 1 detects numbers with digit sequences repeated exactly twice, while Part 2 identifies numbers with any digit pattern repeated at least twice. The workflow parses input ranges from a file, defines validation functions for both parts, runs comprehensive test suites to verify correctness, and processes all ranges to compute final sums.
