This is a straightforward challenge! To solve it:
1. Call the `registerTeam` function with:
- Any non-empty string as the team name
- A team size between 1 and 4
Example solution:
```solidity
challenge.registerTeam("My Team", 2);
```
That's it! The contract will store your team information and mint the flag NFT to your address.
Why this works:
- The name is non-empty, satisfying the first require check
- The team size (2) is between 1 and 4, satisfying the second require check
- The function will automatically mint the flag NFT to your address
Congratulations on getting your first flag! 🎉
