Delegates & Iterators in C#: interview exercises
Delegates & Iterators in C#: 5 test-checked interview exercises (A closure that keeps state), each beside a worked example, with tests as you go. Free.
- A closure that keeps state
- Compose functions
- Memoize a function
- An endless iterator
- A lazy extension method
Each exercise pairs a worked example with a twin problem to solve in a real editor; the tests run the moment you do. Interview mode hides the example: solve it from memory, without the hint or the solution, and it counts as solved cold. Progress is saved in your browser, and in your account if you sign in.
