In what situations is it recommended to use the Sequence data structure?

The Sequence data structure in Android (for example, in Kotlin) represents an ordered collection of elements that supports lazy operations.

It is recommended to use Sequence when:

• You need to process large or potentially infinite data streams without loading the entire volume into memory.
• You want to perform a chain of operations (filtering, mapping, sorting) with minimal resource consumption.
• Performance and memory efficiency through lazy computations are important.

Example: if you have a large list of numbers and need to get the sum of squares of only even numbers, Sequence allows you to do this efficiently:

val numbers = (1..1_000_000).asSequence()
val result = numbers
    .filter { it % 2 == 0 }
    .map { it * it }
    .sum()

Here, operations are performed step-by-step and only as needed, without creating intermediate collections.
