| 01 | Locate integers in the input text, whether a numeric or equivalent English text, e.g., "1" or "one". Add these to find the challenge answer. |
| 02 | Simulate a game consisting of a bag of colored cubes, from which several random handfuls of cubes are taken out and shown. Determine the minimum number of cubes of each color that must be in the bag. |
| 03 | The input is a 2D schematic containing multi-digit part numbers and symbols. The challenge answer is based on finding specific symbols that are adjacent to exactly two numbers and multiplying those numbers. |
