Description

Implement sliding window operation in org.fungover.breeze.util.Arrays to create pairs of adjacent elements.

Implementation Requirements

public static <T> ImmutableList<Tuple2<T, T>> sliding2(T[] array)

• Creates pairs of adjacent elements
• Returns ImmutableList of Tuple2
• Handles arrays shorter than 2 elements
• Thread-safe implementation

Test Cases

• Normal array with multiple elements
• Two-element array
• Single-element array
• Empty array
• Array with null elements
• Large arrays (performance)

Acceptance Criteria

• Method implemented
• 100% test coverage
• Performance benchmarks
• Documentation complete
• Collection variants added
