Move all Zeroes to End of Array

Move all Zeroes to End of Array is a DSA topic. In plain words you use it for a short Move all Zeroes to End of Array example in a short dry-run on paper. Don’t start with a slogan — start with that picture.

Smallest example: the smallest Move all Zeroes to End of Array example you can type. Type it, run it, and say what you see. If you can do that from memory, you know Move all Zeroes to End of Array.

From the example next to this theory: Move all Zeroes to End of Array — arrays give O(1) index access; matrices are arrays of arrays.

Trap — only saying “Move all Zeroes to End of Array” with no example. Fix that before you talk about advanced DSA.

Viva: what is Move all Zeroes to End of Array? Then show the smallest Move all Zeroes to End of Array example you can type. Then name the trap.

What is Move all Zeroes to End of Array? Show this: the smallest Move all Zeroes to End of Array example you can type. Trap: only saying “Move all Zeroes to End of Array” with no example.

Example

arr = [10, 20, 30, 40]
print(arr[2], arr[-1])
matrix = [[1, 2], [3, 4]]
print(matrix[1][0])  # 3

Move all Zeroes to End of Array — arrays give O(1) index access; matrices are arrays of arrays.
