Matchstick problems are among the most exciting topics for developing spatial reasoning.
Usually, there are two types of actions you can perform on problems with matchsticks:
1. Remove the matchstick
2. Move the matchstick
In the first case, your goal is to achieve a structure by completely removing a certain number of matchsticks. In the second case, you should move a specific number of matchsticks to achieve the correct structure.
Ensure that after you move or remove matchsticks, there are no dangling matchsticks.
