This article mainly introduces the LeetCode two-dimensional array how to achieve zero matrix, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let Xiaobian take you to understand.

Topic description:

Write a way of writing that if an element in the Numbn matrix is 0, the row and column in which it is located are 0

For example:

Matrix= [[1, 1, 1], [1, 0, 1], [1, 1, 1]]

Set_zeros_matrix= [[1, 0, 1], [0, 0, 0], [1, 0, 1]]

Arithmetic

Find the location of element 0: I (row), j (column)

Store rows to zero: use tuples to store I and j

Line zero: Matrix [I] = [0] * len (matrix [0])

Column zero: double cycle

Thank you for reading this article carefully. I hope the article "how to achieve Zero Matrix in two-dimensional Array in LeetCode" shared by the editor will be helpful to everyone. At the same time, I also hope that you will support and pay attention to the industry information channel. More related knowledge is waiting for you to learn!
