Скачать или смотреть Handling Large Data Sets with Kotlin Sequences

In Kotlin, sequences are a powerful tool used for manipulating data. Essentially, a sequence is a collection of elements that you can traverse one by one. However, unlike lists or arrays, sequences offer lazy evaluation, meaning computations on elements are only performed when required. This makes them efficient when handling large data sets or performing expensive operations. Sequences are created using the 'asSequence' function or directly by 'sequenceOf' and manipulated using standard functions like 'map', 'filter', etc.



The provided Kotlin code demonstrates the use of sequences. It defines an array of numbers, converts it to a sequence, performs operations (squaring each number, filtering even numbers), and finally converts the sequence back to a list for displaying the result.
