Algorithm Steps

How to Use

  1. Setup: Enter numbers with zeros separated by commas or click "Random with Zeros"
  2. Cleanup: Click "Start Cleanup" to begin the copy over process
  3. Step Through: Click "Next Step" to see each step of the algorithm execution
  4. Run Through: Click "Run Through" to automatically execute all steps in sequence
  5. Observe: Watch how non-zero elements are copied to a new array
  6. Reset: Click "Reset" to start over with a new array

Colors: Blue = Left, Purple = New Position, Red = Zero, Yellow = Copying, Green = Copied

Copy Over Concept

Copy Over is a data cleanup algorithm that removes zeros by copying non-zero elements to a new array.

How it works:

  • Scan original array from left to right
  • When a non-zero element is found, copy it to the new array
  • Increment the new position pointer
  • Continue until all elements are processed
  • Result is a new array with no zeros

Time Complexity: O(n) - single pass through the array
