Why should you care?

Overlapping subproblems need caching.

See it live — copy this example

Run snippets in a .NET console app, LINQPad, or https://dotnetfiddle.net. Write Big O above every solution.

// DP State Design Checklist
// State: dp[i] = ...
// Transition: dp[i] = f(dp[i-1], ...)

What happened?

• Write state meaning in a comment before filling the table.
• Follow the steps below — typing the code yourself is the fastest way to learn.

Practice next

1. Type the snippet in a C# console or LINQPad.
2. Write Big O on top of your solution.
3. Test empty / single-element edge cases.
4. Add a failing test then fix it.
5. Rename variables to domain words.

Remember

You can code a small C# example for DP State Design Checklist. You know the complexity class. You tested at least one edge case.
