I explain the non-zero method, which checks if any specific row on a 2D array contains a zero element. If no zero elements are found, it returns true. I also demonstrate the array resizer class, which includes the num non-zeros method to count rows with all non-zero values, and the resize method to create a new array with only zero methods. Join me as we explore these concepts and their implementation.
