Colors: Blue = Left, Purple = Right, Orange = Legit, Red = Zero, Yellow = Moving, Green = Cleaned
Converging Pointers is a data cleanup algorithm that removes zeros by using two pointers that move toward each other.
How it works:
Time Complexity: O(n) - single pass with two pointers
Scenario: Processing sensor data where 0 indicates a malfunction.
Before: [42, 0, 58, 0, 73, 0, 91]
After: [42, 58, 73, 91]
The converging pointers algorithm efficiently removes faulty readings by swapping from the end, achieving O(n) performance in a single pass. Perfect for real-time systems that need fast cleanup without creating new arrays.
Benefits: Linear time complexity, in-place operation, no extra memory, optimal for large datasets
