Colors: Blue = Left, Purple = New Position, Red = Zero, Yellow = Copying, Green = Copied
Copy Over is a data cleanup algorithm that removes zeros by copying non-zero elements to a new array.
How it works:
Time Complexity: O(n) - single pass through the array
Scenario: A data pipeline extracting valid customer records from raw import data.
Source Array: [101, 0, 205, 0, 308, 0, 412]
Cleaned Array: [101, 205, 308, 412]
The copy over algorithm creates a separate clean array containing only valid records. This is ideal for scenarios where you need both the cleaned data and an audit trail of what was removed. Perfect for data validation pipelines and reporting systems.
Benefits: Preserves original array, creates verified output, maintains data integrity, suitable for immutable data workflows
