Problem Statement
Explain partition, zip, and chunked functions and their use cases.
Explanation
Partition splits a collection into two lists based on a predicate, returning a Pair where first contains elements matching the predicate and second contains non-matching elements. It's perfect for separating data into two categories like valid and invalid items in one pass.
Zip combines two collections into a list of Pairs, matching elements by position, useful for processing parallel arrays or creating coordinate pairs. If collections have different sizes, zip stops at the shortest length, and you can provide a custom transformation instead of creating Pairs.
Chunked breaks a collection into sublists of a specified size, with the last chunk potentially smaller, useful for batch processing or pagination. You can provide a transformation to process each chunk immediately, avoiding storing all chunks in memory.
Examples: numbers dot partition curly it greater 0 curly separates positive and negative, names dot zip ages creates name-age pairs, and list dot chunked 10 creates batches of 10 elements.
