Kodebits Day 95: Lazy Sequences [FREE]
Summary
This short Kotlin challenge demonstrates lazy sequences. It shows how `asSequence()` combined with `map`, `filter`, and `take` processes elements one at a time, evaluating lazily only when a terminal operation is called.
- Kotlin `Sequence` processes elements lazily, one at a time, unlike `Iterable` which processes eagerly.
- Intermediate operations like `map` and `filter` on a `Sequence` are not executed until a terminal operation (e.g., `toList()`) is called.
- `take(n)` on a `Sequence` stops processing after `n` elements are collected, which can optimize performance for large datasets.
