A simple smart contract that lets users associate a name with their favorite number. It allows storing and retrieving favorite numbers by name.
This project is a basic Solidity smart contract that maps a name (string) to a favorite number (uint256). It's ideal for demonstrating how to use mappings, structs, and strings in smart contracts.
Users can:
- Set a favorite number associated with a name
- Retrieve a favorite number by querying the name
