Recruiter screen: a 20-minute phone call, followed by a 1-hour live coding interview.

I was asked to design a pretty simple React component. However, due to nerves and not choosing the best data structure, I didn't arrive at an optimal solution.

Design a React component that functions like an Excel cell.

Each value entered into the component's input should display the value to the right of that component. If you type 'AB' into an input, it should display the values of the cells of 'AB' to the right of the cell.

The cell inputs can accept numbers or letters.
