# Challenge 01
## Problem Statement
You need to copy an array of structs from `calldata` to `storage`. However, directly assigning a `calldata` array to a `storage` array results in a compilation error.
**Task**:
- Refactor the given contract to manually copy the struct array from `calldata` to `storage`.
- Provide your solution and comments in the Discussion for this challenge.
**Constraints**:
- Use Solidity 0.8.x or higher.
**Author**: [Your GitHub Username]
